  五元2-杂芳基2-杂芳族羧酸酯的合成并尝试环化为双歧芳基[2,3- b：3'，2' - d ]吡喃-2-酮

  摘要：

  通过使2-杂芳族羰基氯与2（5 H）-呋喃酮，2（5 H）-噻吩和1-甲基-2（5 H）-吡咯烷在三乙胺中反应制备2-杂芳基2-杂芳族羧酸酯。酯的1 H nmr光谱表明，除了1-甲基-2-吡咯基1-甲基-2-吡咯羧酸酯（5c）以外，两个杂芳族环的电子效应均不会引起任何可观的变化。尝试将酯环化成杂芳基稠合的吡喃-2-酮是不成功的。该结果可以用最稳定的酯构象来解释，其中两个杂原子沿酯基的C 0键为反。

• A New Method for the Synthesis of Carboxylic Esters and Lactones with Di-2-thienyl Carbonate (2-DTC) by the Promotion of DMAP and Iodine

  DOI：10.1246/bcsj.78.1508

  日期：2005.8

  di-2-thienyl carbonate (2-DTC) in the presence of a catalytic amount of 4-(dimethylamino)pyridine (DMAP) proceeded smoothly to afford the corresponding esters in good-to-high yields along with 2(5H)-thiophenone. This esterification was accelerated by the addition of an equimolar amount of iodine to afford the esters in higher yields within a shorter reaction time. Further, cyclization of ω-hydroxycarboxylic

  在催化量的 4-(二甲氨基)吡啶 (DMAP) 存在下，使用二-2-噻吩基碳酸酯 (2-DTC) 将羧酸与醇酯化反应顺利进行，得到相应的酯。与 2(5H)-噻吩酮一起产生。通过加入等摩尔量的碘来加速该酯化，以在更短的反应时间内以更高的产率提供酯。此外，在催化量的 DMAP 存在下，ω-羟基羧酸与等摩尔量的 2-DTC 环化，然后加入 1-4 等摩尔量的碘，以良好到高的产率提供相应的内酯在温和的条件下。该方法成功地用于合成赤霉烯酸内酯。
• Study of<i>cis/trans</i>and<i>endo/exo</i>Diastereoselectivity in the [4+3]-Cycloaddition Reaction of 2-Functionalized Furans and Dimethyloxyallyl Cation: Preparation of Versatile Cycloheptane Synthons

  日期：1997.9

  A study on the influence of steric and electronic effects of a function attached at C-2 of furans in the yield and diastereoselectivity of [4+3] cycloaddition reactions with oxyallyl cations is presented. In almost all studied furans a cis diastereospecificity and a high endo diastereoselectivity is observed. Increasing bulkyness of the function attached at C-2 of furans, increases the endo diastereoselectivity, but decreases yield. Increasing the electronic density of the furan system, by an electron donating group attached at C-2, increases yield and diastereoselectivity.

  本文研究了呋喃的 C-2 上所附函数的立体效应和电子效应对与氧烯丙基阳离子发生 [4+3] 环加成反应的产率和非对映选择性的影响。在几乎所有研究的呋喃中，都观察到了顺式非对映专一性和高度非对映选择性。增加呋喃 C-2 上所附官能团的体积可提高内向非对映选择性，但会降低产率。通过在 C-2 上连接一个电子供体来增加呋喃体系的电子密度，可以提高产率和非对映选择性。

  The total assignment of the 1H and 13C NMR spectra of 24 cis‐endo and 15 cis‐exo diastereoisomers of C‐1‐substituted 2,4‐dimethyl‐8‐oxabicyclo[3.2.1]oct‐6‐en‐3‐one derivatives was deduced from the concerted application of DEPT, COSY, HETCOR, HMBC, HMQC and PS‐NOESY experiments. The relative stereochemistry of major (cis‐endo) and minor (cis‐exo) diastereoisomers was established on the basis of correlation

• Diastereoselective Synthesis of γ-Substituted 2-Butenolides via (CDC)-Rh-Catalyzed Intermolecular Hydroalkylation of Dienes with Silyloxyfurans
  作者：Matthew J. Goldfogel、Courtney C. Roberts、Rajith S. Manan、Simon J. Meek

  DOI：10.1021/acs.orglett.6b03369

  日期：2017.1.6

  Catalytic intermolecular hydroalkylation of dienes with, silyloxyfuran nucleophiles is reported. Reactions hare catalyzed by 5 mol % of a (CDC)-Rh-complex and proceed in up to 87% yield and 6:1 dr (syn/anti) to provide allylic butenolides bearing vicinal stereocenters Reactions proceed with terminal aryl and alkyl dienes and with modified-silyl-enol ether nucleophiles including a thiophenone variant. Utility of the products is demonstrated in the synthesis of a polypropionate anti,syn-stereotriad.
