Description

technical field [0001] The present invention is used in the field of pharmaceutical components for treating or preventing anticholinergic-related diseases, and relates to a novel structure of quaternary ammonium salt-type cyclic amine derivatives, especially 2-(2,2-diarylethenyl)- Quaternary ammonium salt type cyclic amine derivative and its preparation method. Background technique [0002] Organic amine derivatives containing diaryl vinyl groups are an important class of intermediates in drug synthesis, and they also have various pharmacological activities. Brit. J. Pharmacol. 1951, 6, 560-571 reported that a series of tertiary amine type diaryl allylamine compounds (as shown in structure III) have obvious antihistamine, antispasmodic and anesthetic activities. ActaPharmacol.et toxicol.1951, 7, 51-64 found a compound 1,1-diphenyl-3-dimethylamino-butene with a similar structure, which has anticholinergic effect and exhibits obvious antispasmodic activity , also has mild an...
