A concise asymmetric synthesis of chiral bicyclic lactams combining a highly stereoselective 1,2-addition on SAMP hydrazones with a ring closure metathesis has been achieved. The synthetic utility of this approach has been emphasized by the total synthesis of (-)-coniceine in high enantiomeric excess.
已经实现了手性双环内酰胺的简明不对称合成,该合成将 SAMP 腙上的高度立体选择性 1,2-加成与闭环复分解相结合。这种方法的合成效用通过高对映体过量的 (-)-coniceine 的全合成得到了强调。
