A carboxyphenylthiophenylacetic acid compound offor- mula:
in which each of R1 and R2, independently of the other, is a hydrogen or halogen atom or a C1-4 alkyl, C1-4 alkoxy, C1-4 alkylthio, C14 alkylsulfinyl, C1-4 alkyl sulfonyl, trifluoromethyl, trifluoromethylthio, cyano, nitro, di-(C1-4 alkyl)amino, carboxy, or phenyl-(C1-4 alkyl) radical, the phenylalkyl radical optionally having halogen, nitro or C1-4 alkyl substitution in the phenyl ring, is prepared by treating a dianion of the formula (II):
in which R1 and R2 are as defined above, with carbon dioxide in an inert solvent. Such compounds may then be converted to dibenzo-[b,f]-thiepin prostaglandin antagonists by known means.
一种羧基苯硫基乙酸化合物:
其中 R1 和 R2 各自独立地为氢原子或卤素原子或 C1-4 烷基、C1-4 烷氧基、C1-4 烷硫基、C14 烷基亚磺酰基、C1-4 烷基磺酰基、三氟甲基、三氟甲硫基、氰基、硝基、二-(C1-4 烷基)氨基、羧基或苯基-(C1-4 烷基)基,苯基烷基可选择在苯基环上具有卤素、硝基或 C1-4 烷基取代,通过处理式 (II) 的二元离子制备:
其中 R1 和 R2 如上定义,在惰性溶剂中用二氧化碳处理。然后,可通过已知方法将此类化合物转化为二苯并-[b,f]-噻吩类前列腺素拮抗剂。
