Abstract
Abstract The reductive cyclization of α-chloro, bromo- and sulfonyloxycarbonitriles are described. α-Chlorocarbonitriles were reduced by lithium aluminum hydride to afford aziridines in sufficient yields. The Walden inversion was found to take place in the cource of the reductive cyclization of S-α-chloroisocapronitrile. We have found the two-step conversion of aldehydes to 2-mono-substituted aziridines which consists of treating aldehydes with benzenesulfonyl chloride and alkali cyanide to form α-benzenesulfonyloxycarbonitriles which are reduced by lithium aluminum hydride to the corresponding aziridines. The reduction of α-bromocarbonitriles with the hydride yielded prim. amines together with the aziridines.
