stereocontrolled functionalization of conjugated sulfinyl dienes in a cascade process that involves a Michael-type addition, isomerization of a double bond and a [2,3]-sigmatropic rearrangement is reported. Enantioenriched 1,4-diol and 1,4-aminoalcohol derivatives are obtained in a very straightforward manner. Further functionalization of these structures, including highly stereoselective epoxidation,
据报道,在包括迈克尔型加成,双键异构化和[2,3]-σ重排的级联过程中,共轭亚磺酰基二烯的化学和立体控制功能化。以非常直接的方式获得对映体富集的1,4-二醇和1,4-氨基醇衍生物。描述了这些结构的进一步官能化,包括高度立体选择性环氧化,二羟基化和以受控方式立体合成几种多元醇。
