## Abstract As a masked 1,3‐dicarbonyl compound, the 1,1‐dioxo‐__2H__‐1,2‐thiazine‐4‐carbaldehyde 1 undergoes ring transformation with amidines to produce 2‐substituted 4‐methyl‐5‐[1‐methyl‐2‐methylthio‐2‐(__N__‐phenylsulfamoyl)vinyl]pyrimidines 3a–f. For 3b, an X‐ray structure analysis is reported
