  Copper-Catalyzed Synthesis of Substituted Furans and Pyrroles by Heterocyclodehydration and Tandem Heterocyclodehydration–Hydration of 3-Yne-1,2-diols and 1-Amino-3-yn-2-ol Derivatives

  摘要：

  CuCl2-catalyzed heterocyclodehydration of readily available 3-yne-1,2-diols and 1-amino-3-yn-2-ol derivatives afforded substituted furans and pyrroles, respectively, in good to high yields (53-99%) under mild conditions (MeOH as the solvent, 80-100 degrees C, 1-24 h). In the case of 2,2-dialkynyl-1,2-diols, bearing an additional alkynyl substituent at C-2, a cascade process, corresponding to copper-catalyzed heterocyclodehydration followed by acid-catalyzed hydration of the triple bond, was realized when the reaction was carried out in the presence of both CuCl2 and TsOH, leading to 3-acylfurans in one step and high yields (75-84%). Under the same conditions, N-Boc-2-alkynyl-1-amino-3-yn-2-ols were converted into the corresponding N-unsubstituted 3-acylpyrroles in low to fair yields (19-59%). However, working in the presence of added water and a large excess of CO2 (40 atm), in addition to CuCl2 and TsOH, caused a significant improvement of the yields of 3-acylpyrroles (68-87%), thus making the method of general synthetic applicability.

  通过 5-endo-dig 环化快速合成 β-碘呋喃

  摘要：

  使用碘作为亲电子试剂的 3-炔烃-1,2-二醇的 5-endo-dig 环化顺利进行，以提供相应 β-碘呋喃的优异产率。必要的前体可从许多不同的方法中获得，特别是共轭烯炔的区域选择性双羟基化和将乙炔加成到 α-羟基羰基上。最初的碘呋喃可以使用多种策略进行同系化，从各种过渡金属催化偶联到卤素-金属交换以及随后与亲电子试剂的偶联。因此，该方法总体上代表了一种灵活、相对简短且非常有效的方法来处理各种高度取代的呋喃。© Wiley-VCH Verlag GmbH & Co. KGaA，2007 年。

  yields of the corresponding β-iodofurans. The necessary precursors are available from a number of different approaches, notably regioselective bis-hydroxylation of conjugated enynes and the addition of acetylides to α-hydroxy carbonyl groups. The initial iodofurans can be homologated using a number of strategies, ranging from various transition metal-catalysed couplings to halogen-metal exchange and subsequent
