Enantioselective Organocatalytic Amination of Pyrazolones

Enantioselective Organocatalytic Amination of Pyrazolones

Easy as py: The organocatalytic enantioselective amination of pyrazolones is reported. The reaction between pyrazolones and diazodicarboxylates is simple and is catalyzed by quinine to afford the final aminopyarazolone derivatives in excellent yields and good enantioselectivity.
