Direct catalytic asymmetric Mannich-type reaction of unmodified ketones utilizing the cooperation of an AlLibis(binaphthoxide) complex and La(OTf)3·nH2O
The first example of a direct catalyticasymmetric Mannich-type reaction using unmodified ketones and an aminomethyl ether is described. This was achieved by the cooperativecatalysis of a heterobimetallicasymmetric complex (AlLibis(binaphthoxide)) and La(OTf)3·nH2O.
