资源简介：
A highly
diastereo- and enantioselective Mannich-type reaction
of azlactones with aldimines catalyzed by a chiral phosphoric acid
is described. Only 3 mol % catalyst was required to prepare the Mannich
adducts in good yields with high stereochemical control (up to >19:1
dr, >99:1 er). Moreover, the final product contains two consecutive
stereogenic centers, one of which is quaternary.
