从环己烯酮出发,经手性催化的Michael加成反应,Wolff重排反应延长碳链, 再利用重氮化合物的C-H插入反应,以8步反应28.5%的总收率合成了手性β,β '-螺二酮.在合成路线中手性中心的构型保持不变.在最后的检测中未发现另一对 映体,开始产生的手性中心在合成过程没有消旋化。

Starting from cyclohexenone, through catalytic asymmetric Michael addition, homologation by Wolff rearrangement, and finally Rh(II) carbene intramolecular C-H insertion, the enantiomerically pure (R)- spiro[4,5]-decane-2,7-dione was synthesized in 8 steps and 28.5% overall yield. This synthesis further confirms that Rh(n) carbene C-H insertion proceeds with complete retention of configuration.
