An Efficient, One-Pot Synthesis of 3-Alkyl or Aryl Sydnoneimines
摘要:
In a ''one-pot'' process, a variety of 3-alkyl and 3-aryl sydnoneimine hydrochlorides can be prepared in high yield, under mild conditions, by nitrosation of the corresponding aminoacetonitrile with isoamyl nitrite in diethyl ether followed by cyclization with HCl gas.

The synthesis and properties of different types of sydnonimine salts have been investigated. The stability of these salts containing different types of acid components has been examined, and their behaviour towards bases and acids and on catalytic hydrogenation is described. The UV.- and NMR.-spectra of a number of these compounds are given and discussed.

By treatment with bases in methanolic solution N-substituted N-nitroso-amino-acetonitriles (I) undergo an internal rearrangement of the nitroso group to yield α-isonitroso-aminoacetonitriles (II). The structures of the rearrangement products are proved by their physico-chemical properties, by chemical degradation to known products, and by transformation into a number of derivatives.

Oxidation-active flavin mimic, benzo[1,2-g, 5,4-g′]dipteridine (BDP), is found to react with N-nitroso-2-(alkylamino)acetonitrile via oxidative dealkylation in aqueoussolution. From the kinetic investigations, the oxidation mechanism is proposed.
