consisting of Sharpless asymmetric dihydroxylation followed by regioselective breaking of CO bond is utilized to target key chiral intermediates of natural products virolongin B, kigelin, kurasoin A, 4-hydroxy-sattabacin, and actinopolymorphol A. Derivatives of enantiopure hydroxy phenyl propanoids and α-hydroxy Weinreb amides are synthesized. The reductive cleavage of CO bond in a regioselective manner
一种简单的两步策略,包括无尖锐的不对称二羟基化,然后区域选择性打破C O键,可用于靶向天然产物的重要手性中间体,如紫丁香素B,kigelin,kurasoin A,4-羟基-sattabacin和actinopolymorpholA。合成了羟基苯基丙烷和α-羟基Weinreb酰胺。使用甲醇中的Pd / C,可以以区域选择性的方式还原C O键。
