bromoacetyl bromide followed by cyclization in methanolic ammonia gave 5-phenyl-1,3-dihydrobenzo[d′] furo[3,2-e] [1,4]diazepin-2-one, a representative of a new ring-system. The corresponding chloro substituted diazepin-2-one was similarly prepared from 3-amino-2-(4-chlorobenzoyl) benzo[b] furan. Some alkylation and thionation reactions of these diazepines have been investigated.
3-氨基-2-苯甲酰基苯并[ b ]呋喃与溴代乙酰溴反应,然后在甲醇氨中环化,得到5-苯基-1,3-二氢苯并[ d ']呋喃[3,2- e ] [1,4]二氮杂pin -2-one,代表新的环形系统。由3-氨基-2-(4-氯苯甲酰基)苯并[ b ]呋喃类似地制备相应的氯取代的二氮杂-2-酮。已经研究了这些二氮杂的一些烷基化和硫磺化反应。
