Synthesis and Transamination of Enaminones: Derivatives of 1-Phenyl-4-(phenylhydroxymethylidene)-pyrrolidine-2,3,5-trione
摘要:
The reaction of 1-phenyl-4-(phenylhydroxymethylidene)-pyrrolidine-2,3,5-trione with difunctional bases (alpha-,beta-,gamma-amino acid derivatives or aminoethanol) leads to a mixture of tautomeric Schiff bases and enaminones. Some of the products easily undergo transamination at their enaminone moiety.
