3(2 H )‐Furanones are efficiently generated from 3‐alkynyl oxireno[2,3‐ b ]chromenones by an Au/DDQ‐catalyzed domino reaction through a pathway composed of cyclization , CC cleavage, nucleophilic addition , oxidation, and nucleophilic addition . It was found that stoichiometric AuCl 3 or catalytic Au with stoichiometric DDQ can oxidize the benzylic sp 3 CH bond to facilitate nucleophilic addition .
