A novel C-thioacylation reaction is described.Reaction of aromatic or heterocyclic aldehydes with 1-alkyl-2-methyl-1,4,5,6-tetrahydropyrimidine or 1-alkyl-2-methylimidazolidine in the presence of sulphur leads to the thioacylketeneaminals 6,10 or 12 in low to moderate yields.The structure of 6e was proved by S-methylation to 7e and acid-hydrolysis to the known 8e.Oxidative cyclization of 6 leads to the isothiazolo(2,3-a) pyrimidinium salts 13.
