摘要：

The synthesis of the novel tricyclic ring 5‐rnethyl‐4‐oxo‐2,3,4,5‐tetrahydrothiopyrano[3,2‐c]‐[1,2]benzothiazine 6,6‐dioxide (III) is described. By the reaction of hydrazine and hydroxylamine with the glyoxylate (IV) and ester (V) obtained from III, several polyazadithiasteriod analogues have been synthesized.
