Efficient stereochemical controllers in biaryl Suzuki coupling reactions:: Benzylic carbinols bearing in β-position thioether, dimethylamino, or sulfoxide groups

Highly atropo-diastereoselective Suzuki coupling between aryl halides bearing stereogenic benzylic carbinols with sulfoxide, thioether, or dimethylamino groups as efficient internal chelating ligands and 2-methoxy-l-naphthylboronic acid were performed with high yields; a palladacycle is proposed as a potential transition state.
