Synthesis of Enantiomerically Enriched Triarylmethanes by Enantiospecific Suzuki–Miyaura Cross-Coupling Reactions

The Suzuki–Miyaura cross-coupling of chiral, enantio­merically enriched dibenzylic boronic esters is described. The reaction proceeds with almost complete retention of stereo­chemistry, providing access to triaryl­methanes, compounds that have high biological activity and are difficult to prepare in enantio­merically pure form using other methods.
