We report a bismuth(III)triflate catalyzed novel, efficient and atom-economical one-pot three-component methodology for the synthesis of furo[3,2-c]-coumarins from arylglyoxals, 4-hydroxycoumarins and N-substituted anilines. When using N-methyl aniline, we have obtained both the furocoumarins and three-component adducts, whereas with N,N-dimethyl aniline and N,N-diethyl aniline, the reactions proceed well giving only the three-component adducts. Furthermore, these adducts upon treatment with BF3·OEt2 in toluene at 100 °C afforded the desired furo[3,2-c]-coumarins. [ABSTRACT FROM AUTHOR] |
