  • Bismuth(III) triflate catalyzed tandem esterification–Fries–oxa-Michael route to 4-chromanones
    作者:Kevin Meraz、Krishna Kumar Gnanasekaran、Rup Thing、Richard A. Bunce
    DOI:10.1016/j.tetlet.2016.10.005
    日期:2016.11
    An efficient tandem reaction approach is described to prepare 4-chromanones from electron-rich phenols and 3,3-dimethylacrylic acid or trans-crotonic acid in boiling toluene using 20 mol % bismuth(III) triflate as the catalyst. The reaction is also successful from the corresponding aryl esters of each of these acids under the same conditions. The procedure is convenient to perform, and 25–90% yields

    日期:2024.8
    divergent synthesis of chromones and chromanones from a common substrate via reductive coupling cyclization by switching hydrosilanes has been developed. Results of mechanistic studies revealed that under PhMeSiH conditions, the reaction initially undergone cyclization to form chromones , which can subsequently be reduced to yield chromanones . When the hydrosilane was switched to EtSiH, the reaction route
