water, furnished exclusively the (Z)- and ( E )-vinyl sulfides, respectively. The regio- and stereochemistry of the intermediates generated, (Z)- and ( E )-phenylthio vinyl alanates, were determined by capture with iodine, which afforded the corresponding ( E )- and (Z)-1-iodo-1-phenylthio-2-organoyl ethenes. Reactions of the ( E )-iodo(thio)ketene acetals with n-BuLi followed by addition of hexanal
摘要 使用 DIBAL-H 和二(异丁基)-n-(丁基)-铝酸氢化锂(Zweifel 试剂)对硫代乙炔进行加氢铝化,然后加入水,仅提供 (Z)- 和 (E)-乙烯基硫化物,分别。生成的中间体 (Z)- 和 (E)-苯硫基丙二酸乙烯酯的区域和立体化学通过用碘捕获来确定,得到相应的 (E)- 和 (Z)-1-iodo-1-苯硫基-2-有机酰基乙烯。( E )-碘(硫)烯酮缩醛与正丁基锂反应,然后加入己醛,得到(Z)-苯硫代烯丙醇,而(Z)-碘(硫)烯酮缩醛在类似反应条件下得到(E)-苯硫代烯丙醇。
