Substituted oxazol-5-ylethanones can be synthesized in a consecutive three-component sequence starting from propargylamine and various acid chlorides, both for amidation and cross-coupling. Therefore, this diversity-oriented one-pot approach to substituted oxazoles can be considered as an amidation-coupling-cycloisomerization (ACCI) sequence.
