Stille cross coupling protocols were utilized for the synthesis of 3-(biaryl)-8-oxabicyclo[3.2.1]oct-2-ene-2-carboxylic acid methyl esters, which furnished products in high yields where in some cases Suzuki coupling under the conditions utilized provided complex reaction mixture. Samarium iodide reduction of the resulting coupling products produced both of the 2β-carbomethoxy-3-biaryl-8-oxabicyclo[3
Stille 交叉偶联方案用于合成 3-(联芳基)-8-氧杂双环 [3.2.1] oct-2-ene-2-羧酸甲酯,其以高产率提供产品,其中在某些情况下铃木偶联所使用的条件提供了复杂的反应混合物。所得偶联产物的碘化钐还原生成 2β-carbomethoxy-3-biaryl-8-oxabicyclo[3.2.1] 辛烷非对映异构体和 2α-carbomethoxy-3-biaryl-8-oxabicyclo[3.2.1] 辛烷非对映异构体. 在合成的系列中,苯并噻吩取代的化合物表现出显着的抑制 WIN 35,438 的结合谱,对 DAT 与 SERT 的选择性为 177 倍。
