[Reaction: see text]. Readily available N-acylbenzotriazoles 2a-l (derived from a variety of aliphatic, (hetero)aromatic, and N-protected alpha-amino carboxylic acids) smoothly convert primary 3a-c and alpha-functionalized primary nitroalkanes 3d into the corresponding alpha-nitro ketones 5a-p in yields of 39-86% (average 63%).

A novel, highly stereocontrolled formal [3 + 3] annulation of beta-aryl-alpha-nitro-alpha,beta-enals with the enamine derived from 2,2-dimethyl-1,3-dioxan-5-one and pyrrolidine afforded protected nitrocyclitols with five newly created stereocentres and constituted the key step in a short, gram-scale synthesis of a pancratistatin analogue.

Furylfuramide (also known as AF-2)[1] is a synthetic nitrofuran derivative which was widely used as a food preservative in Japan since at least 1965, but withdrawn from the market in 1974 when it was observed to be mutagenic to bacteria in vitro and thus suspected of carcinogenicity. This was confirmed later when animal testing[4] found it to cause benign and malignant tumors in the mammary glands, stomachs, esophagi, and lungs of rodents of both sexes, although insufficient evidence exists in human exposure.[3]

The compounds containing nitro groups when dissolved in basic medium, the following things can happen.

The base can take the $\ce{$\alpha$-H}$ of the nitro-group, which will create a negative charge on that $\ce{$\alpha$-C}$, which can further delocalise with the Nitro-group (similar to Nitro-Acinitro tautomerism).

So, the whole compound will be in the state of a Resonance Hybrid where there will be partial double bond character between $\ce{$\alpha$-C, N }$ and two $\ce O$ atoms. and also there will be a $\delta$- charge on the $\ce{$\alpha$-C }$ atom as well as on the $O$ atoms. , and $\delta$+ charge on the $N$ atoms.Due to such salt like compound formation, it becomes soluble.

This $\delta$- charge created on the Carbon atom is stable if the side chain is short, but starts to get destabilised as the side chain grows longer. So, I think the solubilities of the Nitro-compounds decrease as the side chain grows longer, and the compound with $10-12$ C atoms may not be at all soluble in base because of such large Hydrophobic part and destabilisation of the $\delta$- charge.

Asphalt Nitro is like a shot of nitrous straight to your mobile device, serving up blistering speed and heart-pounding action. Race through stunning, exotic locations, from the neon-lit streets of Tokyo to the sun-soaked beaches of Rio, all while dodging traffic, pulling off gravity-defying stunts, and leaving a trail of burning rubber in your wake.

The single-player career mode consists of six seasons where up to five stars can be earned based on the results. Stars are needed to keep unlocking new events and eventually the next season. Optionally all seasons can be unlocked right away through an in-app purchase. Race types are Classic (race for first place), Versus (compete against one other racer), Elimination (the last racer is eliminated after a certain time), Gate Drift (drift through gates beating a target score with a time limit), Knockdown (the racer with the most knockdowns with a time limit wins), Infected (the last racer receives an infection and can infect other cars; after some time the infection wears off, but wrecks the car; infected races can infect others by bumping into them; infected racers have unlimited nitro and can gain additional time for the infection to wear off by taking out opponents or collecting nitro power-ups), Escape (time based checkpoint race), and Catch (drive a cop car and eliminate opponents by taking them out or using an EMP; opponents can drop mines). For single-player there are also quick races with no rewards. Online multiplayer is available for the racing types Classic, Elimination and Infected. There are also time-limited multiplayer events for special rewards. These require fuel as a currency to enter and it is refilled slowly over time. Only this part of the game has an energy/stamina system. Multiplayer has matchmaking based on a global ranking that is changed with each race.

The game supports four types of control schemes: three based on auto-acceleration (tilt to steer, tap to steer, on-screen controls) and one based on manual acceleration with icons and tilting the device. Reckless and aggressive driving and performing stunts is encouraged to earn rewards. In addition to collecting icons while racing it is also the most important way to acquire nitro, shown in a horizontal meter near the top of the screen. Nitro boost is activated through a tap and it can be hit up to three times with different power levels, but draining faster. There is also a perfect nitro system based on timing a red section in the nitro bar. When approaching a sharp turn, drifting is activated through a tap on the left side of the screen and tapping again ends the drift. Tricks such as a flat spin are performed by entering drift before jumping.

Next to stars to unlock new races and increase the inventory, credits are the most important currency to buy new cars and upgrades. They are provided based on the performances in races with many types of goals. Next to painting a car it can be upgraded four parameters: Acceleration, Handling, Nitro and Top Speed, with seven upgrade levels for each parameter. Credits can also be used to buy kit boxes. They contain common, rare or legendary cards for three main areas (Engines, Parts and Tools) with several sub types. Kit boxes also contain boosters and fuel. Complete sets of cards are used to access upgrades and they can be exchanged with other players. Asphalt tokens are the premium currency to unlock content right away such as premium items, the full racing season, exclusive cars, kit boxes, bundles, additional fuel, boosters, more card inventory slots etc. Boosters that can be bought and are activated prior to a race are double credits, nitro starter, tuning kit (one additional level for each of the four parameters) and extra tank (more nitro capacity). When players buy items with real money they earn VIP points that provide access to up to six VIP levels. VIP levels provides free kits, a reduction of the refresh time for kits, additional fuel cells and a quicker refill, more basic credits, additional upgrade levels and more inventory slots.

The firmware includes an initial implementation for HOTP and TOTP as a second factor. The current version of the command line tool pynitrokey can be used to use these one-time passwords. A new Nitrokey App 2 is already in development to be able to use one-time passwords conveniently via a graphical user interface (GUI) in the future. Currently you can manage OTPs with the alpha firmware using pynitrokey as follows:

The first alpha version of the OpenPGP Card has been further improved and the current version now supports RSA. In summary, RSA 2048, NIST P256 as well as Ed25519 keys can now be generated and RSA 4096 keys can be imported but not generated. In addition, we have improved the compatibility with OpenSC, as well as fixed numerous minor bugs. Please note, if you update from an earlier alpha firmware you need to factory reset the OpenPGP Card with a specific command, otherwise it won't work properly.

Playing Asphalt 7: Heat is a real delight, not least because of its fluid control system. The default control system is based around tilting your device to steer, tapping the left of the screen to brake and the right side to apply nitro. It works very well, but if you want to change the controls in Asphalt 7: Heat you can, and there are four systems to choose from.

Races in Asphalt 7: Heat are thrilling to say the least, and the inclusion of collectible items and insane nitros makes it all the more enjoyable. However, driving at high speeds through some of the more elaborate courses can provoke lag at times, and we experienced this a few times testing on the HTC Sensation.

Gameloft has developed this game with all the licensed cars from the top brands of the world. The gameplay is simple and easy to understand. At the start, you will get to the fleet of VIP cars with features and their stats. The features like acceleration, top speed, handling, nitro, and other ranking factors will help you to decide the car for your race. This racing video game will help you to get your desired racing car.

You are all done with the settings and the race begins. A countdown 3, 2, 1, and you get to go. At the start, you are in the 5th position (5/5/ position). The position of the cars in the race is pop up on the cars. However, a nitrogen boost will take you to the first position (1/5 position). The real task is to maintain this position that merely depends upon your driving skills.

The display screen gives you a better user experience. The top right corner of the screen shows you the number of laps you are racing. In the top middle, a speedometer is there to show you the speed of the car. If you are on a straight and smooth road, the speed of the car may go up to 470 km/h. Moreover, a display below the speedometer shows the speed graphs. Just there, you will find the nitro bar.

At the start of the race, the nitro bar would be on full. However, it would be lowered with the usage and would turn from white to red. The red colour will show that you are running short of nitro. In the top left corner, the display shows your position in the race. This position will be your current position. Besides this, the position is also visible on the racing car as a pop-up display.

The Mod Menu of the game has an option for you to apply nitro in case you are far behind your opponents. In case you strike against a barrier or the opponent or your car has turned upside down, you can apply nitro at once. It will give a boost to your car and you will approach your opponents who are leading towards the winning post.
