The present invention concerns substituted heterocyclic phenoxyamines having the following formula: ##STR1## their pharmacologically acceptable acid salts, their quaternary ammonium salts, their N-oxides, their levorotatory and dextrorotatory isomers and the processes for the preparation thereof. In the above formula: m=0 or 2 n=0 or 2 provided that m+n=2 A represents hydrogen, a lower alkoxy or lower alkenyloxy group, X represents a halogen, R represents hydrogen or a saturated or unsaturated aliphatic and/or cyclic hydrocarbon radical such as in particular lower alkyl, lower alkenyl, cycloalkyl and cycloalkyl-alkyl, cycloalkenyl and cycloalkenyl-alkyl. The compounds of the invention are useful as local anaesthetics.
本发明涉及以下式子的取代杂环苯氧胺:##STR1## 以及它们的药理学上可接受的酸盐、季
铵盐、N-氧化物、左旋和右旋异构体,以及它们的制备方法。在上述式子中:m=0或2,n=0或2,但m+n=2。A代表氢、低烷氧基或低烯氧基,X代表卤素,R代表氢或饱和或不饱和的脂肪和/或
环烃基,例如低烷基、低烯基、环烷基和环烷基-烷基、环烯基和环烯基-烷基。本发明的化合物可用作
局部麻醉剂。
