资源简介:
A highly enantioselective [3 + 2] annulation of MBH carbonates and maleimides catalyzed by chiral phosphines has been developed. In the presence of 5 mol % of l-Thr-l-Val-derived phosphine 6, functionalized bicyclic imides were prepared in excellent yields, and with high diastereoselectivities and nearly perfect enantioselectivities.
