Interphenylene 8-aza-9-dioxothia-11,12-secoprostaglandins are prepared by the two-stage alkylation of the anion of a lower alkyl sulfonamide, R.sup.1 SO.sub.2 NH.sub.2, using first a compound of the formula: ##STR1## and second, a compound of the formula: ##STR2## The compounds produced have renal vasodilatory activity when administered orally and are therefore useful for treating patients with renal impairment.
Interphenylene 8-aza-9-dioxothia-11,12-secoprostaglandins是通过对低级烷基磺酰胺R.sup.1 SO.sub.2 NH.sub.2的负离子进行两阶段烷基化制备的,第一阶段使用公式为:##STR1## 的化合物,第二阶段使用公式为:##STR2## 的化合物。所制备的化合物在口服时具有肾脏扩血管活性,因此可用于治疗患有肾功能障碍的患者。
