[chemical reaction: see text]. A stereoselective total synthesis of the visual pigment A2E has been achieved with use of palladium-catalyzed cross-coupling reactions in all key steps: a regioselective Suzuki or Negishi coupling of 2,4-dibromopyridine, a Sonogashira reaction, and a double Stille cross-coupling to complete the bispolyenyl skeleton.
[化学反应:见正文]。通过在所有关键步骤中使用钯催化的交叉偶联反应,可以实现视觉颜料A2E的立体选择性全合成:2,4-二溴吡啶的区域选择性Suzuki或Negishi偶联,Sonogashira反应和双重Stille交叉反应偶联以完成双聚烯基骨架。
