unactivated ethyl esters with achiral and chiral 1,2-amino alcohols under microwave irradiation and base-free conditions is described. This procedure provides a convenient method for the synthesis of β-hydroxyacetamides bearing pyrazole, imidazole, and benzimidazole groups in high yields and without racemization. The protocol described herein is environmentally friendly and allows for the preparation of a
的酰胺化未活化乙酯与非手性和手性1,2-二氨基微波照射和游离碱条件下醇进行说明。该过程提供了β-hydroxyacetamides轴承吡唑,咪唑和苯并咪唑基团以高产率和无外消旋作用的合成的便利方法。本文所描述的协议是环境友好的,并且允许的各种β-hydroxyacetamides,这是在恶唑啉和生物学感兴趣的其它衍生物的合成中的关键中间体的制备。
