CARBAMIC ACID ESTERS WITH AN ANTICHOLINERGIC ACTION

摘要

The invention relates to novel carbamic acid esters of general formula (1) (see formula 1) in which X- is an anion with a single negative charge, A is a double-bonded group, R1 and R2 are each optionally substituted alkyl or together represent an alkylene bridge, and R3 and R4 each represent hydrogen or optionally substituted alkyl, alkenyl, alkynyl, aryl etc. The invention also relates to a method for producing said esters and to their use as medicaments, in particular medicaments with an anticholinergic action.
