Novel N-Substituted Amino-4-methylsulfanyl-2-pyridones and Deazapurine Analogues from Ketene Dithioacetals
Abstract
A novel synthesis of N-substituted amino-4-methylsulfanyl-2-pyridones and deazapurine analogues via the reaction of ketene dithioacetals with substituted semi- and thio-semicarbazide derivatives is reported and the synthetic potential of the method is demonstrated.
