Abstract

A new strategy has been developed for the synthesis of α-aryl-α-fluoro-β-lactams via the Suzuki cross-coupling of α-bromo-α-fluoro-β-lactam with a range of different aryl-(9-BBN) reagents. This method provides facile access to multisubstituted α-fluoro-β-lactams in a diastereoselective manner. The synthetic utility of α-bromo-α-fluoro-β-lactam has been demonstrated by the arylation of α-bromo-α-fluoro-β-lactam.
