Reaction of diethyl chloromalonate with beta-mercapto amines, 9, gave 1,4-thiazin-3-ones, 10, which were alkylated exclusively at the lactam oxygen with triethyloxonium tetrafluoroborate and subsequently condensed with guanidine to give the first reported 5-thiapterins, 8. Oxidation of 8 with m-chloroperoxybenzoic acid gave the S-oxides, 12. Both 8 and 12 were found to be good inhibitors of rat liver
