The method of preparation of the 3-aryl-6,7,8,9-tetrahydro-5H-imidazo[1,2-a]azepines 2a-d from O-methylcaprolactim and phenacylamine hydrochlorides has been developed. The bases 2 reacted with phenacylbromides to yield the quaternary salts 4a-e. The cyclisation of 4a-e in basic conditions resulted in a new heterocyclic system-the derivatives of 2a,4a-Diazacyclopenta[c,d]azulene-5a-i.
已经开发了由O-甲基己内酯和盐酸苯乙胺制备3-芳基-6,7,8,9-四氢-5 H-咪唑并[1,2 - a ]氮杂2a-d的方法。碱2与苯并溴化物反应生成季盐4a-e。在基本条件下4a-e的环化产生了一个新的杂环系统-2a,4a-二氮杂环戊达[ c,d ] azulene -5a-i的衍生物。
