The synergistic action of BF3·OEt2 and SmI2 allowed a series of intermolecular cross-couplings of readily available N-acyl N,O-acetals with α,β-unsaturated compounds to be performed in high yields, which was applied to the stereoselective synthesis of pyrrolizidine alkaloid (+)-xenovenine.
在 BF3Â-OEt2 和 SmI2 的协同作用下,一系列容易获得的 N-酰基 N,O-乙醛与 δ,δ²-不饱和化合物的分子间交叉偶联反应得以高产进行,并应用于吡咯烷生物碱 (+)-xenovenine 的立体选择性合成。
