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; R.sub.2 stands for hydrogen or a straight or branched C.sub.1 -C.sub.6 alkyl, alkenyl, alkynyl or alkoxy radical, optionally being substituted with halogen, a lower alkoxy or di-(lower alkyl) amino radical; Ar stands for a phenyl radical, optionally being substituted with halogen, lower alkyl, or lower alkoxy; Y stands for oxygen, sulphur or a methylene radical. 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、其盐和酯的方法,以及制备具有一般式的化合物的方法:##SPC1## 其中R.sub.1代表直链或分支的C.sub.1-C.sub.6烷基、烯基或炔基基团,或取代苯基、卤代苯基、三氟甲基苯基、(较低烷氧基)苯基或含有不超过两个来自氧、硫和氮的杂原子的5-或6-成员杂环的C.sub.1-C.sub.3烷基取代基;R.sub.2代表氢或直链或分支的C.sub.1-C.sub.6烷基、烯基、炔基或烷氧基基团,可选择地被卤素、较低烷氧基或二-(较低烷基)氨基基团取代;Ar代表苯基基团,可选择地被卤素、较低烷基或较低烷氧基取代;Y代表氧、硫或亚甲基基团。本发明的化合物在人类和兽医实践中具有明显的利尿和/或盐利尿作用,具有很高的应用价值。
