Abstract

A method for synthesizing substituted 2H-chromenes using TMSOTf-catalyzed polystyrene-supported succinimidyl selenide-induced intramolecular seleno-arylation of tethered alkenes as a key step has been developed. The catalytic process provides an efficient method for the stereoselective and regioselective synthesis of 3,4-dihydro-2H-chromenes possessing a seleno-functionality, followed by syn-elimination of selenoxides to provide 2H-chromenes in good yields and with high purities.
