Catalytic aminomethylation of α,ω-diacetylenes with secondary diamines and aldehydes as an efficient approach to diaza alkatetraynes and tetraaza tetraacetylenic macrocycles

Abstract

An ef cient synthesis of diazaalkatetraynes and tetraaza macroheterocycles by the Mannich aminomethylation of α,ω-di(tetra)acetylenes with secondary diamines and aldehydes using CuCl as a catalyst was developed.
