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. © 2018 American Chemical Society.
