A simple route to 3-aminopyrrolo[2,1-a]isoquinoline, 3-aminopyrrolo[2,1-a]phthalazine, and 7-aminopyrrolo[1, 2-b]pyridazine derivatives 8a, 8b and 11, respectively, is described, based on displacement of a chlorine atom in the appropriate precursors with benzylamine. The chloro-substituted precursors were prepared by using a tandem dichlorocarbene/cycloimmonium ylide approach.
本文介绍了一种分别制备 3-氨基吡咯并[2,1-a]异喹啉、3-氨基吡咯并[2,1-a]酞嗪和 7-氨基吡咯并[1,2-b]哒嗪衍生物 8a、8b 和 11 的简单方法,其基础是用苄胺置换相应前体中的一个氯原子。氯代前体是通过串联二氯甲烷/环亚铵盐方法制备的。
