Butyl lithium converts 5‐substituted‐5,6‐dihydromorphanthridines to the 11‐position anion. Treatment of this lithium anion with aminoalkyl halides affords the 11‐aminoalkylated derivatives. Catalytic hydrogenation causes reductive cleavage of benzylamino bridge of the morphanthridine ring, a reaction which is used to structurally relate these compounds to the known 11‐aminoalkylidene‐5, 6‐dihydromorphanthridines
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.
