Abstract
A convenient method has been developed for the synthesis of the 2‐phenylfuro [2,3‐b]quinoline system. It was found that 3‐formylquinolin‐2(1H)‐one, when reacted with benzylchloride in dry ethanol in presence of potassium carbonate, yielded two intermediates, a hemi‐acetal and an O‐substituted product. The elucidation of these structures by means of 1H‐NMR, 13C‐NMR, and mass spectroscopic methods is reported. Some interesting mass spectral fragmentations were observed for some of the synthesized compounds.
