A stereocontrolled total synthesis of methyl (±)-O-methyl podocarpate (4) has been successfully accomplished using the trans-fused diester 21 as a key intermediate. Intramolecular Michael reaction of the enone-diester 18 afforded the cis-fused keto-diester 19 in high yield which was stereoselectively converted into 21 via the enone 20.
使用反式二酯21作为关键中间体,成功地完成了(±)-O-甲基掌果酸甲酯(4)的立体控制全合成。烯二酯18的分子内迈克尔反应以高产率提供了顺式融合的酮二酯19,其通过烯酮20被立体选择性地转化为21。
