propargylamines in high overall yields (64−77%) by transformation of 1-(arylmethyl)-2-(bromomethyl)aziridines into N,N-di(arylmethyl)-N-(2-propynyl)amines via N-(2,3-dibromopropyl)amines and N-(2-bromo-2-propenyl)amines. The conversion of N-(2,3-dibromopropyl)amines into N-(2-bromo-2-propenyl)amines is based on a novel analogue of the Hofmann elimination. A Yamaguchi−Hirao alkylation, a Sonogashira
通过将1-(芳甲基)-2-(溴甲基)氮丙啶转化为N,N-二(芳甲基)-N-(2-炔丙基)胺通过N-(2,3-二溴丙基)胺和N-(2-溴-2-丙烯基)胺。的转化ñ - (2,3-二溴丙基)胺成ñ - (2-溴-2-丙烯基)胺是基于霍夫曼消除反应的新型类似物。Yamaguchi-Hirao烷基化,Sonogashira偶联或加氢芳基化反应将这些炔丙基胺进一步官能化,成为可能有趣的化合物,可用于医药和农业化学用途。
