Phosphomolybdic acid: a highly efficient solid acid catalyst for the synthesis of trans-4,5-disubstituted cyclopentenones

The furan-2-yl(phenyl)methanol undergoes smooth aza-Piancatelli rearrangement with aryl amines in the presence of 0.03mol% phosphomolybdic acid in acetonitrile under reflux conditions to afford the corresponding trans-4,5-disubstituted cyclopentenone derivatives in good yields with high selectivity...

Zusammenfassung:The furan-2-yl(phenyl)methanol undergoes smooth aza-Piancatelli rearrangement with aryl amines in the presence of 0.03mol% phosphomolybdic acid in acetonitrile under reflux conditions to afford the corresponding trans-4,5-disubstituted cyclopentenone derivatives in good yields with high selectivity in short reaction time.
