The reaction of chiral (hetero)aryl benzyl sulfoxides with Grignard reagents affords enantiomerically pure diarylalkanes in up to 98 % yield and greater than 99.5 % enantiomeric excess. This ligand coupling reaction is tolerant to multiple substitution patterns and provides access to diverse areas of chemical space in three operationally simple steps from commercially available reagents.

conjugate adducts with high diastereoselectivity. Treatment of the adducts with SnCl 4 generated benzyl carbocations which reacted intramolecularly with suitably-positioned aromatic rings to give tetralins and indanes, again with high diastereoselectivity.
