An efficient approach to access functionalized 1,4-and 1,5-amino alcohols has been developed through the nucleophilic addition of semicyclic N,O-acetal with organozinc reagents. A number of substituted benzyl zinc reagents (including nitrile and ester substituted) could react with semicyclic N,O-acetals 1 and 2, affording the desired products 3a−3p and 4a−4o in good to excellent yields.
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.
