compounds reacted with α-benzyloxyaldehyde to afford syn diol exclusively. Further, three contiguous diastereomeric centers were constructed with high stereoselectivity by using (E) or (Z)-crotyl silyl ether. This methodology was applied to the stereoselective synthesis of brassinolide side chain.
在螯合条件下,标题化合物与α-苄氧基醛反应仅得到合成二醇。此外,通过使用(E)或(Z)-巴豆基甲硅烷基醚,以高立体选择性构建了三个连续的非对映异构中心。该方法学应用于油菜素内酯侧链的立体选择性合成。
