1,3-dipolar cycloaddition of stabilized azomethine ylides to alkenyl quinolines: An efficient route to polyfunctionalized 3-pyrrolidinylquinoline derivatives

摘要

Some new polysubstituted 3-pyrrolidinylquinolinyl derivatives were. prepared by 1,3 dipolar cycloadditions of an azomethine ylide, generated in situ from benzylideneimine of methylglycinate and triethylamine in the presence of LiBr, to quinolyl alpha,beta-unsaturated esters.
