Asymmetric imino aza-enamine reaction catalyzed by axially chiral dicarboxylic acid:: Use of arylaldehyde N,N-dialkylhydrazones as acyl anion equivalent

Synthetic utility of arylaldehyde N, N-dialkylhydrazones as a practical acyl anion equivalent could be exploited for the first time in the asymmetric imino aza-enamine reaction catalyzed by axially chiral carboxylic acid.
