The highly convergent synthesis of (R,R)-6,12-dimethylpentadecan-2-one [(R,R)-1], the bioactive form of the sex pheromone produced by female adults of the banded cucumber beetle Diabrotica balteata LeConte, in high enantio- and diastereomeric purity (ee ≥ 99%, de ≥ 98%) and good overall yield (13 steps, 39%) is described. The stereogenic centres were generated by nucleophilic addition of allyltrimethylsilane
(R,R)-6,12-二甲基十五烷基-2-酮[(R,R)-1 ]的高度收敛合成,这是带状黄瓜甲虫Diabrotica balteata LeConte的成年雌性产生的性信息素的生物活性形式,在高对映和非对映纯度(ee值≥99%,德≥98%)和良好的总收率(13个步骤,39%)进行说明。通过将烯丙基三甲基硅烷亲核加成对映体纯的平面手性(π-烯丙基)-四羰基铁(1 +)-络合物,生成立体异构中心。
