Novel 8-aza-9-dioxothiaprostanoic acid compounds, their salts, and derivatives, are prepared from ethyl 7-(3-hydroxymethyl-2-isothiazolidinyl)-5-heptynoate S,S-dioxide by first hydrogenating the triple bond over a Lindlar catalyst, followed by mild oxidation, to produce the corresponding 3-formyl compound, which is condensed with the ylide prepared from dimethyl-(2-oxoheptyl)phosphonate to produce the .alpha.,.beta.-unsaturated ketone, followed by reduction to the corresponding carbinol, and ester hydrolysis. The compounds are useful especially for the treatment of patients with poorly functioning kidneys, as hypotensives, or as platelet aggregation inhibitors.
8-aza-9-dioxothiaprostanoic酸化合物,其盐和衍生物,可通过从乙基7-(3-羟甲基-2-异噻唑啉基)-5-庚炔酸S,S-二氧化物开始,先在Lindlar催化剂上加氢三键,然后进行轻度氧化,以产生相应的3-甲醛化合物,该化合物与从二甲基-(2-氧代庚基)膦酸二甲酯制备的叶立德结构的基团缩合,以产生α,β-不饱和酮,然后还原为相应的醇,并进行酯水解制备而成。这些化合物特别用于治疗肾功能不良的患者,作为降压剂,或作为血小板聚集抑制剂。
