Abstract

2, 4-Disubstituted quinolines have been synthesized by reactions of o-isocyano-β- methoxystyrenes, which can be easily prepared from commercially available o-aminophenyl ketones in three steps, with alkyl (or aryl) lithiums in generally good yields. Subsequently, o- isocyano-β-methoxystyrenes have also proved to react efficiently with lithium dialkylamides to afford the corresponding 4-substituted N, N-dialkylquinolin-2-amines in satisfactory ...
