    Substrate-Directed Diastereoselective Hydroformylation: Key Step for the Assembly of Polypropionate Subunits
    摘要:
    Stereoselective hydroformylation of methallylic alcohols of types 3 and 4, that employed the substrate-bound catalyst-directing ortho-diphenyl-phosphanylbenzoyl (o-DPPB) group, was used as a key step for the construction of bifunctionalized stereotriads, which ale central building blocks of polyketide natural products. The required diastereomerically pure syn- and anti- starting methallylic alcohol systems 3 and 4 were obtained either by Cram-selective carbonyl reduction, Frater alkylation, or by chelation-controlled carbonyl reduction. Enantiomerically pure stereotriad building blocks were derived from a combination of an Evans aldol addition and subsequent o-DPPB-directed stereoselective hydroformylation (-->24). A crystal structure analysis for steretriad building block 24 confirmed the relative and absolute configuration of the stereogenic centers. Additionally, it provided evidence for a previously postulated preferred conformation of the catalyst-directing o-DPPB group as well as of the polyketide main chain.

  • Stereoselective Hydroformylation:  Key Step for the Assembly of Polypropionate Subunits

    achieved. The basis of this result was a careful substrate design making use of a syn-pentane interaction as the decisive stereochemical control element. Confirmation of this working hypothesis came from conformational analysis studies on alkenic substrate 16 employing 2D NOESY experiments in solution and MACROMODEL/MM3 calculations. This stereoselective, transition metal-catalyzed, C-C bond-forming
    已经实现了具有优异平的无环立体控制的2-亚丙基取代的1,3-二恶烷16、17和26的抗选择性加氢甲酰基化。该结果的基础是使用正戊烷相互作用作为决定性立体化学控制元素的仔细的底物设计。对该工作假设的证实来自对烯属底物16的构象分析研究,该研究在溶液中进行了2D NOESY实验,并进行了MACROMODEL / MM3计算。这种立体选择性的,过渡属催化的CC键形成反应可以作为构建全反和同反立体三单元构建基20、21和31的关键步骤,应该非常适合于目标定向聚丙烯酸酯的合成。

    日期:1993.3
    Epoxidation of the strained allylic ethers 7 proceeds with low or very high diastereofacial selectivity, depending on the relative configuration of the methyl group next to the allylic alkoxy group. The magnitude of this asymmetric induction is interpreted in terms of transition-state models similar to a model proposed by Houk
    取决于烯丙基烷氧基旁边的甲基的相对构型,应变的烯丙基醚7的环氧化以低或非常高的非对映选择性进行。这种非对称感应的幅度是根据类似于Houk提出的模型的过渡状态模型来解释的
