Ag(I)-promoted Decarboxylative Annulation of α-Oxocarboxylic Acids with (E)-3-(2-aminophenyl)-1-Phenylprop-2-en-1-ones Toward 3,4- Functionalized Quinolines

An efficient Ag-promoted decarboxylative cyclization of α-oxocarboxylic acids with (E)-3- (2-aminophenyl)-1-phenylprop-2-en-1-ones has been developed to afford a series of functionalized quinolines in moderate to good yields. This method was compatible with a variety of functional groups and provided an attractive method toward phenyl(2-phenylquinolin-3-yl)methanones.
