Reductive Cyclodimerization of α, β- Unsaturated Ketones Promoted by AlCl3/Sm System: A Facile Synthesis of 2-Aroyl-1,3,4-triaryl Cyclopentanol Derivatives
Abstract
Promoted by AlCl3/Sm bimetallic system, α, β-unsaturated ketones underwent reductive cyclodimerization to afford cyclopentanol derivatives under mild conditions. The reaction is stereocontrolled and regioselective over the competitive carbon-carbon double bond reduction.
