The reactions of Z-rich unsaturated Weinreb amides with organolithium and organocerium reagents were examined. Taking in consideration both the extent of geometry retention and cleanness of the reaction, organocerium reagents were more effective for the conversion to Z-α,β-unsaturated ketones.
研究了富含 Z 的不饱和 Weinreb 酰胺与
有机锂和有机
铈试剂的反应。考虑到几何形状的保留程度和反应的清洁度,有机
铈试剂在转化为 Z-α,β-不饱和酮方面更为有效。
