A Sm(II)-mediated, asymmetric, intermolecular ketyl-olefin addition employing α,β-unsaturated esters linked to resin through an ephedrine âchiral linkâ has been applied in a direct âasymmetric catch-releaseâ approach to γ-butyrolactones.
一种以Sm(II)为媒介的非对称分子间酮基-烯烃加成反应,采用通过“麻黄碱手性连接”与树脂相连的α,β-不饱和酯,已被应用于直接的“非对称捕获-释放”方法,以合成γ-丁内酯。
