carbamates react with retention of configuration, thereby providing enantio‐complementary routes to β‐hydroxy allylsilanes (see scheme). The methodology has been applied in a concise formal total synthesis of (−)‐decarestrictine D.
另一面:(-)-半胱氨酸络合的锂化氨基甲酸酯与β-硅烷基乙烯基硼烷反应,构型反转,而不含二胺的锂化氨基甲酸酯则与构型保留反应,从而提供了对β-羟基烯丙基硅烷的对映体-互补途径(参见方案) )。该方法已用于简明的(-)-去卡地丁D的正式总合成中。
