Graphical Abstract

Abstract

A regio- and diastereoselective ring-expansion reaction of N-acylaziridines is described for the synthesis of 4-carboxamide oxazolines using InCl3. A domino Ugi–Joullié/ring-expansion reaction of arylphenylazirines, isocyanides, and carboxylic acids leads to the target products through the N-acylaziridine intermediates in the presence of the indium catalyst. The oxazolines were synthesized in moderate to excellent yields with high atom economy and high bond-forming efficiency under mild reaction conditions.
