Popis:	It is demonstrated by 13C NMR spectroscopy that the dipyrimidothiazines that are formed in the reaction of 1,3-dimethyl-5-nitro-6-chlorouracil with 4-R-5-amino-6-mercaptopyrimidines are dipyrimido[4,5-b][4′,5′-e] [1,4]thiazines. The tautomeric transformations of these compounds were studied.
