Abstract

Abstract N, N-dialkyl-N′-chlorosulfonylchloroformamidines 1 were treated with 2- aminothiazoline, 2-aminothiazoles, 2-aminobenzothiazoles, 2-amino-1, 3, 4-thiadiazoles, and 2-amino-1, 3, 4-oxadiazoles to give a 6, 7-dihydrothiazolo [3, 2-b][1, 2, 4, 6] thiatriazine dioxide 3, a 6, 7-dihydrothiazolo [2, 3-c][1, 2, 4, 6] thiatriazine dioxide 4, thiazolo [3, 2-b][1, 2, 4, 6] thiatriazine dioxides 5,[1, 2, 4, 6] thiatriazino [3, 2-b] benzothiazole dioxides 7, a [1, 2, ...
