Two concise, highly convergent strategies for the synthesis of Vitamin D derivatives are presented. Beginning with synthons of exceedingly low complexity, each approach utilizes a transition metal catalyzed intramolecular carbometalation for the stereoselective formation of the critical (bis)exocyclic diene subunit.
提出了两种简洁,高度收敛的维生素D衍生物合成策略。从复杂性极低的合成子开始,每种方法都利用过渡金属催化的分子内碳金属化来形成关键的(双)外环二烯亚基立体选择性形成。
