Abstract

Reactions of 5acetyl1arylalkyl6methyl4methylsulfanylpyrimidine21Hthiones prepared from diacetylketene NSacetal with guanidine afforded 3alkyl and 3aryl7amino5methyl4methylidene34dihydropyrimido45dpyrimidine21Hthiones Byproducts of these reactions 5acetyl1alkylaryl6methyl2thiouracils can also be obtained from the starting pyrimidinethiones and EtONa in EtOH Pyrimidopyrimidinethiones can react with MeOH at the methylidene group in the presence of MeONa
