Article abstract of DOI:10.1007/BF00472400

Heterocyclization of 5,6-disubstituted 2-allylthio(oxy)-4-oxothieno<2,3-d>pyrimidines by treatment with halogens affords thieno<3,2-e>thiazolo<3,2-a>pyrimidine iminium salts.Treatment of these salts with aqueous sodium acetate results in cleavage of the thiazoline ring.
