Catalytic enantio- and diastereoselective Mannich reaction of α-substituted isocyanoacetates and ketimines

Abstract

The highly diastereo- and enantioselective Mannich addition/cyclisation reaction of α-substituted isocyanoacetate ester pronucleophiles and (hetero)aryl and alkyl methyl ketone-derived ketimines using a silver acetate and a cinchona-derived amino phosphine binary catalyst system is reported.
