Significance

This article reports on the Suzuki-Miyaura coupling of enantioenriched α-(acylamino)benzylboronic acid that surprisingly proceeds with inversion of stereoconfiguration.

Comment

Strong intramolecular coordination of the carbonyl group to boron is considered responsible for the preferred backside attack of the palladium complex on the benzylic carbon atom.
