A regioselective phosphonylation of quinolines for the synthesis of α-amino quinolinyl phosphonamides and γ-amino quinolinyl phosphonamides has been developed under mild reaction conditions. An NHP-thiourea enables selective synthesis of α-amino quinolinyl phosphonamides by a Reissert-type reaction, and an NHP-tosylamide affords γ-amino quinolinyl phosphonamides via a 1,4-conjugate addition reaction. The corresponding amino quinolinyl phosphonate adducts were obtained in moderate to excellent yields (up to 99% yield) and regioselectivities (up to 99:1) with good functional group tolerance.
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.
