Abstract
We demonstrate that configurationally stable anomeric stannanes undergo a stereospecific cross-coupling reaction with aromatic halides in the presence of a palladium catalyst with exceptionally high levels of stereocontrol. In addition to a broad substrate scope (>40 examples), this reaction eliminates critical problems inherent to nucleophilic displacement methods and is applicable to (hetero)aromatics, peptides, pharmaceuticals, common monosaccharides, and saccharides containing free hydroxyl groups.
