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. This strategy provides orthogonal access to electron-deficient heteroaromatic compounds, which are traditionally synthesized by transition metal catalyzed cross-couplings, and circumvents common issues associated with proto-demetalation and β-hydride elimination.

Heavily-substituted 1-aryltetralins and 1-arylindanes were prepared in a highly stereoselective manner using a two-step sequence. Addition of t-butyl benzyl sulfoxides to unsaturated carbonyl compounds gave conjugate adducts with high diastereoselectivity
