    在Heronapyrrole C的全合成和羧酸天然产物类似物的制备过程中对2-硝基-4-烷基吡咯的合成努力
    摘要:
    研究了与硝基吡咯和相关天然产物有关的2-硝基-4-寡聚戊二烯基取代的吡咯衍生物的合成。在众多方法中,使用AcONO 2硝化3-法呢基取代的未保护吡咯的效果最佳,尽管收率和区域选择性仍不令人满意。因此,检查了(-)-heronapyrrole C酸的合成,该酸是天然存在的抗生素heronapyrrole C的类似物,其带有生物等位羧酸盐而不是硝基。代替不令人满意的硝化反应,用Cl 3进行区域选择性酰化进行了CCOCl(与硝化作用的比例为1:1.3相比,区域选择性> 8:1)。在合成的最后阶段,在卤代反应中将三氯甲基酮转化为所需的酸。模拟合成的其他关键步骤涉及位置和立体选择性的Corey-Noe-Lin二羟基化反应和有机催化的双Shi环氧化反应。仿生聚环氧环化级联反应建立了双THF主链。因此,由市售起始原料以八个步骤(14.5%的总产率)合成了(-)-戊基吡咯C酸。

  • METHODS FOR FORMING SATURATED (HETERO)CYCLIC BORYLATED HYDROCARBONS AND RELATED COMPOUNDS

    The disclosure relates to methods for forming at least partially saturated cyclic and heterocyclic borylated hydrocarbons, as well as related compounds, which can be precursor compounds in the synthesis of any of a variety of pharmaceutical or medicinal compounds with a desired structure and/or stereochemistry for drug synthesis or drug candidate evaluation. The methods generally include reduction of an unsaturated cyclic or heterocyclic borylated hydrocarbon having a boron-containing substituent at an sp 2 -carbon, where such reduction converts the sp 2 -carbon to an sp 3 -carbon at the point of attachment of the boron-containing substituent. The methods can exhibit a selectivity for syn-addition during reduction, which can provide stereospecific products, such as when the unsaturated cyclic or heterocyclic reactant is multiply substituted with boron groups and/or other functional groups.
    本发明涉及用于形成至少部分饱和的环状和杂环硼化烃的方法,以及相关的化合物,这些化合物可以是合成多种具有所需结构和/或立体化学的药物或药用化合物的前体化合物。这些方法通常包括将具有sp2碳上含硼取代基的不饱和环状或杂环硼化烃还原,这样的还原将sp2碳转化为与含硼取代基连接点上的sp3碳。这些方法在还原过程中可表现出对顺式加成的选择性,从而可以提供立体特异性产物,例如当不饱和环状或杂环反应物上多元取代硼基团和/或其他功能基团时。

    我们报告了一种通过芳烃加氢将易得的甲硅烷基化芳烃转化为甲硅烷基化饱和碳和杂环的方法。范围包括烷氧基和卤代甲硅烷基取代基。甲硅烷基可被衍生为多种功能,并在有机合成,材料科学以及制药,农业化学和香料研究中得到应用。但是,目前的技术很难获得甲硅烷基化的饱和(杂)循环。氢化的产率取决于硅胶添加剂的量。这种二氧化硅效应还可以显着改善以前公开的高度氟化芳烃的氢化方法(例如,氢化至全顺式C 6 H 6 F 6)。

    a little does the trick! The catalytic enantioselective arylation using chiral dicationic palladium complexes provides a reliable and useful access to enantiomerically enriched mandelic‐acid derivatives. Significantly low catalyst loading (down to 0.002 mol %) as well as easy catalyst handling are the advantage of this practical method.

  • Catalytic and highly enantioselective Friedel–Crafts type reactions of heteroaromatic compounds with trifluoropyruvate and glyoxylate by a dicationic palladium complex
    作者:Kohsuke Aikawa、Yuya Asai、Yūta Hioki、Koichi Mikami

    The highly enantioselective Friedel-Crafts alkylation of furan and thiophene derivatives with trifluoropyruvate, which have never provided the high level of asymmetric induction and yield until now, was achieved by using dicationic palladium complexes as Lewis acid catalysts. Moreover, glyoxylate instead of trifluoropyruvate as an electrophile led to complete change of regioselectivity with 2-trimethylsilylated furan, thiophene, and pyrrole derivatives to give the corresponding heteroarylated products in high yields and enantioselectivities. The respective products with trifluoropyruvate and glyoxylate could also be obtained via sequential catalytic reaction; intramolecular cyclization of alkynyldiols using cationic Au catalyst followed by Friedel-Crafts type reactions using dicationic Pd catalyst.
