A Simple and Economic Synthesis of Propargylamines by CuI-Catalyzed Three-Component Coupling Reaction with Succinic Acid as Additive

Abstract

A practical and efficient method was developed for the synthesis of propargylamines in a one-pot procedure from aldehydes, amines, and alkynes by using CuI as catalyst and succinic acid as additive. By using this protocol, a wide range of propargylamines was obtained in high yields.
