    Enantioselective synthesis of sabina ketone
    摘要:
    Both enantiomers of sabina ketone were efficiently prepared via an easy synthesis of 1-diazo-5-methylene-6-methylheptan-2-one, starting from succinic anhydride, followed by its highly enantioselective cyclization catalyzed by chiral dirhodium(II) compounds having ortho-metalated phosphines as ligands.

  • PtCl<sub>2</sub>-Catalyzed Cycloisomerizations of 5-En-1-yn-3-ol Systems
    作者:Youssef Harrak、Christophe Blaszykowski、Matthieu Bernard、Kevin Cariou、Emily Mainetti、Virginie Mouriès、Anne-Lise Dhimane、Louis Fensterbank、Max Malacria

    5-En-1-yn-3-ol substrates bearing a free hydroxyl group or an acyl group are highly versatile partners for PtCl2-catalyzed cycloisomerizations. Electrophilic activation of the alkyne moiety triggers at wish a hydride or an O-acyl migration yielding at the end to regioisomeric keto derivatives. The efficient preparation of Sabina ketone, an important monoterpene precursor, has been worked out.
    带有游离羟基或酰基的 5-En-1-yn-3-ol 底物是 PtCl2 催化的环异构化的通用伙伴。炔烃部分的亲电活化可触发氢化物或 O-酰基迁移,最终产生区域异构酮衍生物。已经研究出重要的单萜前体Sabina酮的有效制备。

    into the bicyclic cyclopropyl ketone derivatives 5 and 6 by way of a gold-catalyzed Ohloff-Rautenstrauch-type enyne cycloisomerization is described. The required substrates were prepared by an asymmetric addition of the branched allylzinc reagent 21 to the alkynyl aldehyde 17 mediated by the deprotonated bisoxazoline (BOX) ligand 22. Compounds 5 and 6 were then converted into a host of different members
    描述了通过金催化的Ohloff-Rautenstrauch-型烯炔环异构化的方法简单地进入双环环丙基酮衍生物5和6。通过将非支化的烯丙基锌试剂21不对称地添加到由去质子化的双恶唑啉(BOX)配体22介导的炔基醛17中来制备所需的底物。然后将化合物5和6转化为倍半胱氨酸和倍半熟的不同成员的主体。萜类化合物,尤其是在铁催化的交叉偶联反应的帮助下。由于可以清楚地确定5和6的相对和绝对构型,因此合成样品允许解开各种此类萜类化合物以前未知的立体结构,包括顺式倍半萜烯水合物(33),7-表倍半萜烯(36),倍半萜烯B(37)和环氧倍半萜烯(45)。此外,6的制备也构成了塞得烯(11)和塞多尔(12)的正式全合成。

    1,5-Enynes are highly reactive under PtCl2 catalysis and give a range of [3.1.0] bicyclic skeletons. The scope and limitations of this process are presented. Regioisomeric keto derivatives are obtained depending upon the nature of the oxygenated substituent at the propargylic position of the starting substrate.

    2-Cycloalken-1-one 1,4-di --benzyl -L-threitol ketals undergo efficient and diastereoselective cyclopropanation when treated with an excess of the Simmons-Smith reagent. For example, 2-cyclohexen-1-one 1,4-di --benzyl -L-threitol ketal gave in 90-98% yield a 9:1 mixture of diastereomeric cyclopropanes as established by 62.9 MHz 13C NMR spectroscopy and by hydrolysis of the mixture to (1,6)-bicyclo[4
    当用过量的Simmons-Smith试剂处理时,2-Cycloalken-1-one 1,4-二--苄基-L-苏糖醇缩酮会发生高效且非对映选择性的环丙烷化。例如,由62.9 MHz 13 C NMR光谱法和水解确定,2-环己烯-1-酮1,4-二-苄基-L-苏糖醇缩酮的收率为90-98%,为非对映体环丙烷的9:1混合物将混合物制成(1,6 )-双环[4.1.0]庚烷-2-酮。给出了十六个其他实例,这些实例证明了2-环烯-1-酮缩酮的制备方法的一般性和可预测性,因为不幸的是,它对α,β-不饱和1,4-二-苄基-L-苏糖醇缺乏非对映选择性乙缩醛。
