[chemical reaction: see text]. A stereoselective total synthesis of the visual pigment A2E has been achieved with use of palladium-catalyzed cross-couplingreactions in all key steps: a regioselectiveSuzuki or Negishi coupling of 2,4-dibromopyridine, a Sonogashirareaction, and a double Stille cross-coupling to complete the bispolyenyl skeleton.
