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
描述了 α-氯、溴和磺酰氧基腈的还原环化。α-氯代腈被氢化铝锂还原,得到足够产率的氮丙啶。发现瓦尔登反转发生在 S-α-氯异己腈的还原环化过程中。我们发现了醛向 2-单取代氮丙啶的两步转化,其中包括用苯磺酰氯和碱金属氰化物处理醛以形成 α-苯磺酰氧基腈,后者被氢化铝锂还原为相应的氮丙啶。用氢化物还原 α-溴代腈产生 prim。胺与氮丙啶。
