Enantioselective Conjugate Arylation of Maleimides

The resulting chiral C—N axis could then be used as a good template to control the configuration of subsequent transformations as was shown for alkylation and Diels-Alder processes. 

Additional Acceptors for Rhodium/Diene-Catal]rzed Conjugate Aiylation 

Recently, Hayashi reported the details of a rhodium/diene-catalyzed 1,4-addition of organoboron reagents to quinone monoketals 108, which provides a rapid access to a-arylated tetralones in high yield and stereoselectivity [94].
