The present invention relates to a series of new compounds, their salts and esters and to methods for the preparation of the compounds having the general formula: ##SPC1## In which R.sub.1 represents a straight or branched C.sub.1 -C.sub.6 alkyl, alkenyl or alkynyl radical, or a C.sub.1 -C.sub.3 alkyl radical substituted with phenyl, halophenyl, trifluoromethylphenyl, (lower alkoxy)phenyl, or with a 5-membered or 6-membered heterocyclic ring containing not more than two heteroatoms selected from the group consisting of oxygen, sulphur and nitrogen; Ar stands for a phenyl radical, optionally being substituted with halogen, lower alkyl, hydroxy, or lower alkoxy; Y stands for O, S, NH or a CH.sub.2 radical; and YR.sub.1 is placed in the 2- or 3-position. The compounds of the invention which are valuable in the human and veterinary practice, possess a pronounced diuretic and/or saluretic activity.
本发明涉及一系列新化合物,它们的盐和酯,以及制备具有以下一般式的化合物的方法:
其中R.sub.1代表直链或支链C.sub.1-C.sub.6烷基,烯基或炔基基团,或者被苯基、卤代苯基、三氟甲基苯基、(较低的烷氧基)苯基取代的C.sub.1-C.sub.3烷基基团,或者含有不超过两个氧、硫和氮所选杂原子的5-或6-成员杂环的烷基基团;Ar代表苯基基团,可以选择地被卤素、较低烷基、羟基或较低烷氧基取代;Y代表O、S、NH或CH.sub.2基团;YR.sub.1放置在2-或3-位置。本发明的化合物在人类和兽医实践中具有显著的利尿和/或排钠活性。
