Asymmetric α-amination of 4-substituted pyrazolones catalyzed by a chiral Gd(OTf)3/ N,N′-dioxide complex: Highly enantioselective synthesis of 4-amino-5-pyrazolone derivatives

The asymmetric α-amination of 4-substituted pyrazolones with azodicarboxylates was investigated for the first time, employing an N,N′-dioxide gadolinium(III) complex as the catalyst. The novel transformations exhibited high yield, and 4-amino-5-pyrazolone
