A Practical Method for Oxazole Synthesis by Cycloisomerization of Propargyl Amides
摘要:
2,5-Disubstituted and 2,4,5-trisubstituted oxazol-5-yl carbonyl compounds were prepared in good yields by a mild SiO2-mediated cycloisomerization of propargyl amides.

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 amidationâcouplingâcycloisomerization (ACCI) sequence.

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.
