Intermolecular Couplization and Cyclization of Chalcones Promoted by Samarium in DMF
摘要:
Under mild and neutral conditions, reductive coupling-cyclization of chalcones was promoted by samarium metal with an activator in DMF to afford products in good to excellent yields. The reaction is regioselective over the competitive carbon-carbon double-bond reduction and stereocontrolled.
