A novel synthesis of 5‐acylaminooxazoles

Abstract

1,2‐Diacylamino‐1,2‐di(benzotriazol‐1‐yl)ethanes 2, easily prepared from the condensation of 1,2‐di(benzotriazol‐1‐yl)ethane‐1,2‐diol 1 and primary amides, were converted to 5‐acylaminooxazoles in good to moderate yields via intramolecular cyclization upon treatment with sodium hydride.
