Synthesis of the tittle compounds has been achieved starting with the new tricyclic ring, 6-methyl-4-oxo-3,4-dihydro-2H,6H-thiopyrano[3,2-c][2,1]benzothiazine 5,5-dioxide (III). This compound was converted to the glyoxylate VI, the β-ketoester IX, a difluoride complex XIII and an enamino ketone XXIV which, by hydrazine, hydroxylamine and glycine treatment, gave 7,11-dithiaazasteroid analogues.

从新的三环,6-甲基-4-氧代-3,4-二氢-2 H,6 H-硫代吡喃并[3,2- c ] [2,1]苯并噻嗪5开始,已经完成了标题化合物的合成。,5-二氧化物(III)。将该化合物转化为乙醛酸酯VI,β-酮酯IX,二氟化物络合物XIII和烯胺酮XXIV,通过肼,羟胺和甘氨酸处理,得到7,11-二硫杂氮杂甾类类似物。通过分别用氯丙酮和肼处理,还从酮VIII和β-二酮X中获得了一些意想不到的产物。
