The Pd-catalyzed asymmetric allylic alkylation (Pd-AAA) of enol carbonates derived from γ-butyrolactones is reported, affording the corresponding enantioenriched α,α′-disubstituted γ-butyrolactones in both high yields and high enantioselectivities (up to 94% ee). This method was eventually applied to the synthesis of chiral spirocyclic compounds.
据报道,由γ-丁内酯衍生的烯醇碳酸酯的Pd催化不对称烯丙基烷基化(Pd-AAA),可提供高产率和高对映选择性(高达94%ee)的相应的对映体富集的α,α'-二取代γ-丁内酯。 。该方法最终应用于手性螺环化合物的合成。
