A new synthesis of leukotriene B3 methyl ester is reported, starting from bis(trimethylsilyl) unsaturated derivatives as building blocks for the triene moiety of the leukotriene. The two stereogenic centers have been generated by enantioselective chemical reduction of two acetylenic ketones with both R- or S-Alpine BoraneR. The three conjugated double bonds system of the leukotriene has been assembled
从双(三甲基甲硅烷基)不饱和衍生物作为白三烯三烯部分的结构单元开始,报道了白三烯B 3甲酯的新合成。通过用R-或S-高山硼烷R对映体选择性化学还原两个炔酮,生成了两个立体异构中心。白三烯的三个共轭双键系统已经通过宫浦铃木交叉偶联反应组装。
