REGIOSPECIFIC SYNTHESIS OF N-1 AND N-2 SUBSTITUTED PYRIMIDONES EMPLOYING A NOVEL 1,3-OXAZINE PREPARATION
Reaction of ethyl benzoylacetate with methylthiopseudourea resulted in expulsion of methylmercaptan to afford 2-amino-6-phenyl-4H-1,3-oxazin-4-one in good yield.This novel oxazine synthesis was exploited to secure N-1 and N-2 substituted pyrimidinones regiospecifically.
