Spasmolytic endo-8,8-dialkyl-8-azoniabicyclo (3.2.1) octane-6,7-exo-epoxy-3-alkyl-carboxylate salts

摘要

The invention relates to new products, namely endo-8,8-dialkyl-8-azoniabicyclo [3.2.1] octane-6,7-exo-epoxy-3-alkylcarboxylates, of formula: <IMAGE> in which R1 and R2, which can be the same or different, are linear or branched alkyl radicals of 1-5 C atoms or cycloalkyl radicals of 3-6 C atoms; R3 and R4, which can be the same or different, are alkyl radicals of 1-6 C atoms; X- is a halide ion. The new compounds are powerful spasmolytics.
