    • The present invention is directed to 2-hydroxy-4-alk­ylidenecyclohexanealkanoic acids having a mercaptoalkanoic acid substituent at the 3-position. Esters and amides corresponding to the acids referred to above are also encompassed by the present invention. These compounds are useful in the treatment of bronchial asthma and they are obtained by the reaction of an appropriate 2,3-epoxy-4-­alkylidenecyclohexanealkanoate with a mercapto alkanoic acid ester in the presence of a tertiary amine. The indi­cated process gives the esters of the present invention which can be hydrolyzed to the corresponding free acids by standard procedures. The compoudns described can be sub­jected to other known reactions to give the other compounds of the present invention.
    • 本发明涉及在3-位具有巯基链烷酸取代基的2-羟基-4-亚烷基环己烷链烷酸。 对应于上述酸的酯和酰胺也包括在本发明中。 这些化合物可用于治疗支气管哮喘,它们通过适当的2,3-环氧-4-亚烷基环己烷链烷酸酯与巯基链烷酸酯在叔胺存在下反应而得到。 所示方法得到本发明的酯,其可通过标准程序水解为相应的游离酸。 所描述的化合物可以进行其他已知的反应以得到本发明的其它化合物。
