The optically active lactone 1 can be transformed to a chiral building block or intermediate for constructing carbon skeletons containing either a tertiary or quaternary stereogenic center by taking advantage of the steric bulk as well as the reactivity of a trimethylsilyl group at the β-position of 1.
旋光内酯1可以转化为手性结构单元或中间体,以通过利用空间体积以及1的β位置上的三甲基甲硅烷基的反应性来构建包含叔立体中心或叔立体中心的碳骨架。。
