  A Convergent and Highly Efficient Synthesis of (E,Z)-2,13-Octadecadienyl Acetate and (E,Z)-3,13-Octadecadienyl Acetate, Components of the Sex Pheromone of the Leopard Moth Zeuzera pyrina, through Sulfones

  摘要：

  [GRAPHICS]A new, convergent synthesis of (E,Z)-2,13 octadecadienyl acetate (1) and (E,Z) 3,13 octadecadienyl acetate (2), the two key components of the leopard moth Zeuzera pyrina, from 2 chloromethyltetrahydrofuran in good overall yields and stereomeric purity is reported. The synthesis of both components utilizes the common intermediate sulfone 12 as a convenient building block to be coupled with iodoacetylenic derivatives 9 or 17 in the key step.

  secondary propargylic alcohols in good yields to provide trans enals and enones exclusively. Readily available indenylbis(triphenylphosphine)ruthenium chloride, in the presence of indium triflate and camphorsulfonic acid, gives the best turnover numbers and reactivity with the broadest range of substrates. Deuterium labeling experiments suggest that the process occurs through propargylic hydride migration

  催化钌配合物与铟助催化剂和布朗斯台德酸一起以良好的产率异构化伯醇和仲炔醇，以专门提供反式烯醛和烯酮。在三氟甲磺酸铟和樟脑磺酸存在下，现成的茚基双（三苯基膦）氯化钌可提供最佳的转化率和对最广泛底物的反应性。氘标记实验表明，该过程是通过炔丙基氢化物迁移随后产生的乙烯基钌中间体的质子裂解发生的。这种方法在白三烯 B4 的合成中的应用证明了它的实用性和非凡的选择性。
