The totalsynthesis of the natural (8E,15E,22E)-heptatriaconta-8,15,22-trien-2-one and (15E,22E)-heptatriaconta-15,22-dien-2-one is reported. Our synthesis involved a modular and convergent approach, based on the copper-catalyzed addition of Grignardreagents to allylic olefins. The obtention of these methyl ketones is an important asset for the use of these compounds as analytical patterns with application
天然(8 E ,15 E ,22 E )-heptatriaconta-8,15,22-trien-2-one和(15 E ,22 E )-heptatriaconta-15,22-dien-2-one的全合成据报道。我们的合成涉及一种模块化和收敛的方法,基于铜催化格氏试剂加成烯丙基烯烃。获得这些甲基酮是将这些化合物用作分析模式并应用于地球科学的重要资产。
