本文提出了一种简单、绿色、高效的合成苯并恶唑和苯并噻唑的方法。该方法以邻氨基酚、邻氨基硫酚、脂肪族或芳香族醛为原料，在水相介质中，以三氟化钐为催化剂，在温和的反应条件下进行反应。
Abstract A simple, green, and efficient method is presented for the synthesis of benzoxazoles and benzothiazoles from reaction of o-aminophenols, o-aminothiophenols, and aliphatic or aromatic aldehydes using samarium triflate as a reusable acid catalyst under mild reaction conditions in aqueous medium.
