Synthesis of the title compounds has been achieved starting from 4-oxo-3,4-dihydro-2H,5H-thiopyrano[3,2-c][1]benzothiopyran 6,6-dioxide (III), which was converted to glyoxylate (IV), β-ketoester (V), difluoride complex (VII) and β-diketone (XII) gave with hydrazine, hydroxyl-amine and glycine ethyl ester several azadithiasteroid analogues.
从4-氧代-3,4-二氢-2 H,5 H-硫代吡喃并[3,2- c ] [1]苯并噻喃6,6-二氧化物(III)开始合成了标题化合物将乙醛酸酯(IV),β-酮酸酯(V),二氟化物络合物(VII)和β-二酮(XII)与肼,羟胺和甘氨酸乙酯一起制得几种氮杂二氮杂甾类类似物。
