Synthesis of selenated isochromenones by AgNO3-catalyzed three-component reaction of alkynylaryl esters, selenium powder and ArB(OH)(2)

摘要

Reported is the AgNO3-catalyzed three-component reaction of alkynylaryl esters, selenium powder and ArB(OH)(2), providing a facile entry to selenated isochromenones. This work highlights the use of selenium powder as a selenium reagent in the synthesis of selenated isochromenones for the first time.
