    Salinipyrones and Pacificanones, Mixed-Precursor Polyketides from the Marine Actinomycete Salinispora pacifica
    摘要:
    Chemical examination of a phylogenetically unique strain of the obligate marine actinomycete Salinispora pacifica led to the discovery of four new polyketides, salinipyrones A and B (1, 2) and pacificanones A and B (3, 4). These compounds appear to be derived from a mixed-precursor polyketide biosynthesis involving acetate, propionate, and butyrate building blocks. Spectral analysis, employing NMR, IR, UV, and CD methods and chemical derivatization, was used to assign the structures and absolute configurations of these new metabolites. Salinipyrones A and B displayed exactly opposite CD spectra, indicating their pseudoenantiomeric relationship. This relationship was shown to be a consequence of the geometric isomerization of one double bond. The phenomenon of polyketide module skipping is proposed to explain the unusual biosynthesis of the salinipyrones and the pacificanones.

    通过布朗斯特或路易斯酸催化开发 α,α-二取代巴豆基硼酸酯试剂和立体选择性巴豆基化
    摘要:
    报道了 α,α-二取代巴豆基硼酸酯试剂的开发。手性布朗斯台德酸催化不对称醛加成与开发的 E-巴豆基硼试剂产生 (E)-anti-1,2-oxaborinan-3-enes,具有优异的对映选择性和 E-选择性。在 BF3·OEt2 催化下,立体选择性被逆转,并且从相同的 E-巴豆基硼试剂中获得了具有优异 Z-选择性的 (Z)-δ-硼基-抗高烯丙醇。Z-巴豆基硼试剂还参与BF3·OEt2催化的巴豆化反应以提供具有良好Z-选择性的(Z)-δ-硼基-syn-高烯丙醇。DFT 计算确定了观察到的手性布朗斯台德酸催化的不对称烯丙基化的对映选择性和立体选择性的起源。BF3·OEt2 催化反应的立体化学模型被提出来合理化Z-选择性烯丙基加成。这些反应生成具有立体定义的三取代烯烃单元的高价值高烯丙醇产品。Salinipyrones A 和 B 的全合成进一步证明了合成效用。

  • Development of α,α-Disubstituted Crotylboronate Reagents and Stereoselective Crotylation via Brønsted or Lewis Acid Catalysis

    Stereochemical models for BF3·OEt2-catalyzed reactions are proposed to rationalize the Z-selective allyl additions. These reactions generate highly valuable homoallylic alcohol products with a stereodefined trisubstituted alkene unit. The synthetic utility is further demonstrated by the total syntheses of salinipyrones A and B.
