    Synthesis of Substituted Pyridines via Regiocontrolled [4 + 2] Cycloadditions of Oximinosulfonates
    摘要:
    Diels-Alder cycloadditions of oximinosulfonate 8 with a variety of 1,3-dienes proceed with regiochemistry opposite to that observed with conventional imino dienophiles, providing expeditious synthetic routes to substituted pyridines, tetrahydropyridines, and pyrrolines. The oximinosulfonate 8 is prepared in one convenient synthetic operation from Meldrum's acid and reacts with conjugated dienes at -78 degrees C in the presence of 2 equiv of dimethylaluminum chloride to afford [4 + 2] cycloadducts in good to excellent yield. Exposure of these cycloadducts to the action of NaOMe and N-chlorosuccinimide in methanol-THF at room temperature then produces substituted pyridines. The utility of this new two-step annulation protocol is demonstrated in total syntheses of the pyridine alkaloids fusaric acid and (S)-(+)-fusarinolic acid. Heating the [4 + 2] cycloadducts derived from 8 in a mixture of acetonitrile and pH 7 phosphate buffer induces an unusual Stieglitz-type rearrangement leading to the formation of interesting spirobicyclic pyrrolines.

    elongated aromatic and aliphatic tertiary alcohols (C5–C15) that contain a specific signature motif demonstrate the broad substrate specificity of LinD. The three-dimensional structure of LinD from Castellaniella defragrans revealed a pentamer with active sites at the protomer interfaces. Furthermore, the structure of LinD in complex with the product geraniol provides initial mechanistic insights into
    醇的不对称脱水是直接合成烯烃的重要过程。我们报告的结构和底物特异性的双功能芳樟醇脱水酶异构酶(LinD)从自然界中催化β-月桂烯水合到芳樟醇和随后的异构化成香叶醇的Castellaniella defragrans细菌。包含特定特征基序的截短和延长的芳香族和脂肪族叔醇(C5-C15)的酶促动力学拆分证明了LinD具有广泛的底物特异性。林德从三维结构Castellaniella defragrans揭示了一个五聚体,在前体界面处具有活性位点。此外,LinD与香叶醇产物复合的结构为这种双功能酶提供了初步的力学见解。定点诱变证实了其脱水和异构化活性必不可少的活性位点氨基酸残基。这些结构和机理的见解促进了水合催化剂的开发,丰富了用于新型键形成生物催化的工具箱。
