Reactions of organocuprates with vinyl-triflates and related cephems: A novel approach to 3-substituted cephalosporins

Vinyl-triflates and related 3-substituted cephems readily undergo addition-elimination reactions with a variety of organocuprates to form new carbon-carbon bonds. This chemistry presents a novel approach to the synthesis of 3-alkyl, 3-aryl, and 3-alkenylcephalosporins.
