Synthesis of novel tryptamine-based macrocycles using an Ugi 4-CR/microwave assisted click-cycloaddition reaction protocol†
Abstract
A practical synthesis of novel tryptamine-based macrocycles using an Ugi 4-CR/click-cycloaddition sequential reaction protocol is described. The main features of the macrocyclic scaffolds are a peptoid moiety, a 1,3-substituted indole nucleus, and a triazole ring.
