The novel fused heterocyclic systems 7,8,13,14-tetrahydrobenzo[b]naphtho[1,2-f][1,5]diazocine and 7,8,13,14-tetrahydrobenzo[b]naphtho[2,1-f][1,5]diazocine were prepared in moderate yields in a one step reaction by Vilsmeier formylation of 1-dimethyl-aminonaphthalene or 2-dimethylaminonaphthalene, respectively, by way of the ‘t-amino effect’. Novel rearranged by-products were formed from 2-dimethylaminonaphthalene.
                                    新颖的杂环系统7,8,13,14-四氢苯并[b]
萘[1,2-f][1,5]二氮杂烯和7,8,13,14-四氢苯并[b]
萘[2,1-f][1,5]二氮杂烯通过Vilsmeier甲酰化反应,分别以适中的产率在一步反应中由1-
二甲氨基萘或2-
二甲氨基萘制备而成,利用了“t-
氨基效应”。从2-
二甲氨基萘中形成了新颖的重排副产物。
