First Example of a 4-Amino-1,2,4,6-thiatriazine 1,1-Dioxide Derivative
摘要:
For the first time, an N-4-amino derivative of 1,2,4,6-thiatriazine 1,1-dioxide (5) was prepared by cyclocondensation reaction of the appropriate sulfamoylcarbamate (3) with hydrazine. Reaction of 3 with ammonia yielded the cyclic 4H-derivative (4). Nucleophilic substitution reactions of 4 and 5 with hydrazine, as well as condensation of 5 with ethyl orthoformate were achieved. The antiprotozoal and anti-HIV properties of the new compounds were evaluated, but none of them showed significant biological activities.

Novel 1,2,4,6-thiatriazine 1, 1-dioxides substituted at either the 2 or 4 ring nitrogen atom have been prepared by cyclizing sulfamido-iso(thio)urea derivatives.
