A new consecutive three-component oxazole synthesis by an amidation–coupling–cycloisomerization (ACCI) sequence

Abstract

A novel consecutive three-component synthesis of 1-(hetero)-aryl-2-(2-(hetero)aryl-oxazol-5-yl) ethanones starting from propargyl amine and acid chlorides, both for amidation and cross-coupling, is based upon an amidation-coupling-cycloisomerization (ACCI) sequence.
