Enantioselective Direct Amination of α-Cyanoacetates Catalyzed by Bifunctional Chiral Ru and Ir Amido Complexes
摘要:
The bifunctional chiral amido Ir complex catalyzed asymmetric electrophilic direct amination of alpha-substituted alpha-cyanoacetates using azodicarboxylates proceeds rapidly to provide the corresponding hydrazine adducts in high yields and with excellent ea values.
