of the marinoquinoline family of natural products, together with the related marine alkaloid aplidiopsamine A (12), have been synthesized using various combinations of palladium-catalyzed Ullmann cross-coupling and reductive cyclization processes involving a C3-arylated pyrrole as the common intermediate. These natural products have been characterized by single-crystal X-ray analyses and evaluated as
使用钯催化的Ullmann交叉偶联和涉及C3的还原环化过程的各种组合合成了代表天然产物马来喹啉家族主要成员的化合物1-6和11,以及相关的海洋生物碱Aplidiopsamine A(12)。 -芳基吡咯为常见中间体。这些天然产物已通过单晶X射线分析进行了表征,并被评估为乙酰胆碱酯酶(AChE)的抑制剂,同类物2被证明是活性最高的。
