The asymmetric epoxidation of 2‐oxoindoline‐3‐ylidene acetaldehydes, catalyzed by diarylprolinol silyl ether, has been developed. The reaction provides oxindole derivatives possessing chiral epoxides in good yield with good diastereoselectivity and excellent enantioselectivity.
已开发了由二芳基脯氨醇甲硅烷基醚催化的2-氧代吲哚啉-3-亚乙基乙醛的不对称环氧化。该反应以良好的收率,良好的非对映选择性和优异的对映选择性提供了具有手性环氧化物的羟吲哚衍生物。
