摘要

Abstract 7-Amino-1H, 4H-imidazo [2, 3-c][1, 2, 6] thiadiazine 5, 5-dioxide was prepared by a multi-step reaction sequence form 3, 5-diamino-4H-1, 2, 6-thiadiazine 1, 1-dioxide. 7-Amino- 4H-furazano-[3, 4-c][1, 2, 6] thiadiazine 5, 5-dioxide was obtained by lead tetraacetate oxidation of 3, 5-diamino-4-hydroxyimino-4H-1, 2, 6-thiadiazine 1, 1-dioxide.
