Synthesis of chiral cyclobutanes via rhodium/diene-catalyzed asymmetric 1,4-addition: a dramatic ligand effect on the diastereoselectivity†
Abstract
A highly diastereo- and enantioselective rhodium-catalyzed arylation of cyclobutenes for the efficient synthesis of chiral cyclobutanes has been developed. Chiral diene ligands exhibited excellent capability for the reaction diastereoselectivity control.
