  • Control of Regioselectivity by the <i>l</i><i>one</i> Substituent through Steric and Electronic Effects in the Nitrosoarene Ene Reaction of Deuterium-Labeled Trisubstituted Alkenes
    作者:Waldemar Adam、Oliver Krebs、Michael Orfanopoulos、Manolis Stratakis
    DOI:10.1021/jo026198i
    日期:2002.11.1
    For the ene reaction of 4-nitronitrosobenzene (ArNO) with a variety of primary and secondary lone alkyl-substituted substrates, the twix/twin regioselectivity is constant at about 85:15. In contrast, for the lone tert-butyl group and for lone aryl substituents, the twix regioisomer is obtained exclusively. These regioselectivities have been rationalized in terms of steric interactions and coordination
    对于4-硝基亚硝基苯(ArNO)与多种伯和仲孤烷基取代的底物的烯反应,twix / twin区域选择性恒定在约85:15。相反,对于单独的叔丁基和对于单独的芳基取代基,仅获得twix区域异构体。这些区域选择性已经在第一步反应的过渡态中,在亲和体与底物之间的空间相互作用和配位方面得到了合理化。

    the C-H bond, which is diastereoselectively attacked, and steric strain between the remaining substituents at the stereogenic and the prostereogenic center is minimized. DFT calculations support this model. They suggest, however, that the reaction is not concerted but occurs via hydrogen atom abstraction and subsequent radical rebound.

  • Asymmetric Total Syntheses of Aetheramides and Their Stereoisomers: Stereochemical Assignment of Aetheramides
    作者:Na Qi、Srinivasa Rao Allu、Zhanlong Wang、Qiang Liu、Jian Guo、Yun He
    DOI:10.1021/acs.orglett.6b02371
    日期:2016.9.16
    The concise total syntheses of the potent HIV inhibitors aetheramides A and B (IC50 values of 15 and 18 nM), as well as three pairs of their stereoisomers, were achieved, which allowed the complete stereochemical assignment of aetheramides for the first time. With a longest linear sequence of 15 steps, the convergent, fully stereocontrolled route provided aetheramides A and B in 5.3% and 3.6% yields
    有效的HIV抑制剂醚酰胺A和B(IC 50值为15和18 nM)以及三对立体异构体的简明总合成得以实现,这是首次实现了醚酰胺的完全立体化学归属。具有15个步骤的最长线性序列,收敛,完全立体控制的路线分别提供了5.3%和3.6%的醚酰胺A和B含量。合成策略的特征在于有效的Stille偶联用于大环化,不对称的羟醛反应以在C-17和C-26处建立歧义的立体化学,以及实施温和的条件以避免敏感的聚酮化合物部分的差向异构化和不稳定的内酯的迁移。
