A TiII-mediated, stereo- and regio-specific reduction of isolated, conjugated and methylene skipped poly-ynes to the corresponding Z-dideuterio polyenes in a one-pot procedure with D2O as deuterium source is described, and this methodology (using H2O) is applied to the synthesis of (3E,8Z,11Z)-tetradeca-3,8,11-trienyl acetate, the major sex attractant of Scrobipalpuloides absoluta, a destructive pest of tomatoes.
该研究描述了以 D2O 作为
氘源,通过 TiII 介导的、立体和区域特异性还原分离的、共轭的和亚甲基跳变的聚炔,并将这种方法(使用
H2O)应用于合成 (3E,8Z,11Z)-tetradeca-3,8,11-trienyl acetate(一种西红柿毁灭性害虫 Scrobipalpuloides absoluta 的主要性引诱剂)。
