Facile route for novel quinazolinone-fused azauracils through cyclodesulfurization of thioquinazolinones

Abstract

An efficient, novel, short, and high-yielding one-pot protocol for the synthesis of diverse quinazolinone-fused azauracil heterocycles through cyclodesulfurization and intramolecular cyclization of thioquinazolinone using silver cyanate is described. © Georg Thieme Verlag Stuttgart.
