Abstract:

Reactions of 3-(polyfluoroacyl)chromones with indole and N-methylindole in refluxing pyridine and N-methylpyrrole under solvent-free conditions proceed at the C(2) atom of the chromone system with pyrone ring opening and subsequent cyclization to 2-hydroxy-3-(indol-3-ylmethylene- or pyrrol-Z-ylmethylene)-2-(polyfluoroalkyl)chroman-4-ones in good yields. Treatment of these compounds with morpholine gives trans-indolyl(pyrrolyl)chalcones.
