NaBH3CN reduction of symmetric dimers in which two steroid units are linked by a 1,4-dimethylidenebenzene moiety followed two different courses: (a) hydrogenation of the benzylic double bond and (b) reductive F ring opening of the side chain. While courses a and b led to symmetrical dimers, the combination of both pathways produced an unsymmetrical dimer that bears different side chains in each half
NaBH 3 CN 还原对称二聚体,其中两个甾体单元通过 1,4-二亚甲基苯部分连接,遵循两个不同的过程:(a)苄基双键的氢化和(b)侧链的还原性 F 开环。虽然路线a和b导致对称二聚体,但两种途径的组合产生了不对称的二聚体,其在每一半中带有不同的侧链。给出了所有获得的化合物的详尽 NMR 表征。
