The synthesis of series of 1α and 1β‐alkylamino‐1,2,3,4,5,6‐hexahydro‐2,6‐methano‐3‐benzazocines from the corresponding acylamino intermediates is described. Cyclization of the 1β‐chloromethylamido derivative 20 to the novel bridged benzomorphan 21 occurred whereas the corresponding 1β‐chloromethylamido derivative 19 failed to cyclize for steric reasons. In addition several related 1α‐acylamidomethyl‐ and 1β‐alkyl‐aminomethyl benzomorphans are reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
