A convenient solid-phase synthesis of coumarins by TMSOTf-catalyzed intramolecular seleno-arylation of tethered alkenes

TMSOTf-catalyzed intramolecular seleno-arylation of tethered alkenes was performed using polystyrene-supported succinimidyl selenide as the selenium source. This catalytic process provides an efficient method for the regioselective synthesis of dihydrocou

Palladium-catalyzed synthesis of 4-arylcoumarins using triarylbismuth compounds as atom-Efficient multicoupling organometallic nucleophiles

Triarylbismuth compounds have been cross-coupled as atomefficient multicoupling organometallic nucleophiles with. 4bromo- and 4- (trifluoromethylsulfonyloxy)coumarins under palladium catalysis conditions. These reactions afforded an array of 4-arylcoumari
