资源简介：
A highly diastereoselective and enantioselective Michael
addition
of α-substituted isocyanoacetates with maleimides catalyzed
by bifunctional tertiary amine thioureas has been developed. Various
chiral succinimide derivatives bearing adjacent quaternary and tertiary
stereocenters were prepared in excellent yields (up to 98%), diastereoselectivities
(up to 99:1), and enantioselectivities (up to 98% ee). The synthetic
utility of chiral succinimide derivatives is also demonstrated in
the preparation of h5-HT1d receptor agonist motifs.
