The present invention concerns new derivatives of 1-aryl 2-aminomethyl cyclopropane carboxylates (Z), their preparation and their use as useful drugs for the treatment of various pains. The new derivatives of the present invention have the general formula I ##STR1## in which: R represents a hydrogen or halogen atom, a C.sub.1 to C.sub.4 lower alkyl group, a C.sub.1 to C.sub.4 lower alkoxy group, or a nitro, amino, sulfamoyl or hydroxy group; n represents the values 1, 2 or 3; (R).sub.n may together with the benzene ring also form the naphthyl group; R.sub.1 represents a linear or branched C.sub.1 to C.sub.5 alkyl or alkenyl group or an aryl or benzyl group; R.sub.2 and R.sub.3 represent a hydrogen atom, a linear or branched C.sub.1 to C.sub.5 alkyl, alkenyl, alkynyl, hydroxyalkyl, alkoxyalkyl, carboxyalkyl or dialkylaminoalkyl group or an aryl, arylalkyl or cycloalkyl group; R.sub.2 and R.sub.3 possibly also forming a heterocycle of 5 or 6 members with the adjacent nitrogen atom, provided however that when R.sub.1 represents the ethyl radical and R represents a hydrogen atom, R.sub.2 and R.sub.3 cannot simultaneously represent a methyl radical.
本发明涉及1-芳基2-氨甲基环丙烷羧酸酯(Z)的新衍生物,其制备和用作治疗各种疼痛的有用药物。本发明的新衍生物具有一般式I
其中:R代表氢或卤素原子,C.sub.1到C.sub.4低级烷基,C.sub.1到C.sub.4低级烷氧基,或硝基,氨基,磺酰氨基或羟基基团;n表示值1、2或3;(R).sub.n可以与苯环一起形成萘基;R.sub.1代表线性或支链的C.sub.1到C.sub.5烷基或烯基基团或芳基或苄基基团;R.sub.2和R.sub.3代表氢原子,线性或支链的C.sub.1到C.sub.5烷基,烯基,炔基,羟基烷基,烷氧基烷基,羧基烷基或二烷基氨基烷基基团或芳基,芳基烷基或环烷基基团;R.sub.2和R.sub.3还可以与相邻的氮原子形成5或6成员的杂环,但当R.sub.1代表乙基基团且R代表氢原子时,R.sub.2和R.sub.3不能同时代表甲基基团。
