Palladium Catalysis in Cephalosporin Chemistry: General Methodology for the Synthesis of Cephem Side Chains

We describe in full the palladium-catalyzed coupling of 3-(triflyloxy)cephems with organotin compounds, leading to the synthesis of 3-alkenyl-, 3-alkynyl-, and 3-arylcephems under exceptionally mild conditions.While this approach was not satisfactory for
