Cholinergic Agents Structurally Related to Furtrethonium. 2. Synthesis and Antimuscarinic Activity of a Series of N-[5-[(1'-Substituted-acetoxy)methyl]-2-furfuryl]dialkylamines
In the first part of this study, devoted to the discovery of selective antimuscarinic agents, (+/-)- N-[5-[(1'-phenyl-1'-cyclohexylacetoxy)methyl]-2-furfuryl]dimeth yla mine (5a) proved to be at least 20 times more potent in the rat ileum and bladder than in guinea pig atria. Several (+/-)-N- [5-[(1'-substituted-acetoxy)methyl]-2-furfuryl]dialkylamine analogs of 5a were subsequently prepared. This
