Synthesis of 11-<i>cis</i>-Retinoids by Hydrosilylation-Protodesilylation of an 11,12-Didehydro Precursor: Easy Access to 11- and 12-Mono- and 11,12-Dideuteroretinoids

An expeditious, highly efficient approach to 11‐cis‐retinoids was achieved by semihydrogenation of a readily available 11‐yne precursor through a hydrosilylation–protodesilylation protocol. The complete chemo‐, regio‐, and syn‐stereoselectivity of the method also allowed direct access to 11‐ and 12‐monodeutero‐, and 11,12‐dideutero‐11‐cis‐retinoids. The analogous trans series was not accessible by
一种快速,高效的11-顺-维甲酸类化合物的方法是通过氢化硅烷化-脯氨酰化方法对现成的11-炔前体进行半氢化而实现的。完整的化疗,区域选择性和SYN方法-stereoselectivity也让其11-和12- monodeutero-,和11,12二氘11-直达顺-retinoids。通过该途径无法获得类似的反式序列,并且是通过Hiyama耦合合成的。
