Optically active oxirane-2-carboxylic esters, prepared from allylic alcohols employing the Sharpless epoxidation, were treated with sodium azide. The azido alcohols obtained were subsequently converted into aziridine-2-carboxylic esters by reaction with triphenylphosphine, in good yields and with high optical purity. Various racemic oxirane-2-carboxylic esters were subjected to the same sequence of
用叠氮化钠处理由使用Sharpless环氧化的烯丙基醇制备的旋光环氧乙烷-2-羧酸酯。随后通过与三苯基膦反应以高收率和高光学纯度将获得的叠氮基醇转化为氮丙啶-2-羧酸酯。使各种外消旋环氧乙烷-2-羧酸酯进行相同的反应顺序。
