Abstract
A simple one-pot procedure for the preparation of symmetrical bis-hydrazone functionalized barbiturates, and a step-by step sequence for the synthesis of analogous unsymmetrical derivatives were developed. Their treatment in acid conditions furnish the symmetrical- and unsymmetricalspirobarbiturate- pyridines, respectively.File in questo prodotto:
