The ozonation of substituted 2-thiouracils and pyrimidine-2-thione is reported; this provides a new method for the synthesis of several pyrimidine derivatives.

The synthesis of 6-alkyl and 5,6-dialkyl-2-methoxy-4(3H)-pyrimidinones 3 is described. Their versatility to be transformed into 6-alkyl and 5,6-dialkyluracils 4(a-h), 6-alkyl and 5,6-dialkyl-3-methyluracils 7(a,e,f) and 6-alkyl and 5,6-dialkyl-2-alkoxy-4(3H)-pyrimidinones 5(a-i) is also shown.
