Abstract

Simple, effective, and high yield synthetic procedures for formylation and acetylation of barbituric acid derivatives is described. Generated 5-acylbarbituric acids are transformed into the corresponding Schiff bases in high yield condensation reactions with ω- aminoalkanoic acids and nitrophenylhydrazines.
