  • Catalytic Preparation of Cyclic Carboxylic Esters
    申请人:Spindler Felix
    公开号:US20090275761A1
    公开(公告)日:2009-11-05
    Preparation of cyclic esters by hydrogenation of a carbonyl group in at least one anhydride radical —C(O)—O—C(O)— of a cyclic dicarboxylic or polycarboxylic anhydride by means of hydrogen in the presence of a homogeneous noble metal catalyst, characterized in that the hydrogenation is carried out in a homogeneous reaction mixture using an iridium catalyst. The cyclic esters are obtained in good chemical and optical yields when prochiral anhydrides are used together with chiral iridium catalysts.
    通过在至少一个环状二羧酸酐基团—C(O)—O—C(O)—中的羰基团上加来制备环,所述环状二羧酸酐为环状二羧酸酐或多羧酸酐,通过在均相贵金属催化剂存在下使用氢气,在均相反应混合物中使用催化剂进行化反应。当使用外消旋酸酐与手性催化剂一起时,可以获得良好的化学和光学产率。
  • Stereoselective Synthesis of δ-Lactones from 5-Oxoalkanals via One-Pot Sequential Acetalization, Tishchenko Reaction, and Lactonization by Cooperative Catalysis of Samarium Ion and Mercaptan
    作者:Jue-Liang Hsu、Jim-Min Fang
    DOI:10.1021/jo016058t
    日期:2001.12.1
    sequence of acetalization, Tishchenko reaction and lactonization. The deliberative use of mercaptan, by comparison with alcohol, is advantageous to facilitate the catalytic cycle. The reaction mechanism and stereochemistry are proposed and supported by some experimental evidence. Such samarium ion/mercaptan cocatalyzed reactions show the feature of remote control, which is applicable to the asymmetric synthesis
    通过sa离子和醇的协同催化,一系列5-代烷醛以有效和立体选择性的方式转化为(取代的)δ-内。这一一锅法包括一系列缩醛化,Tishchenko反应和内化。与醇相比,有意使用醇有利于促进催化循环。提出了反应机理和立体化学,并得到了一些实验证据的支持。sa离子/醇共催化反应显示出远程控制的特征,适用于旋光性δ-内的不对称合成。这项研究还证明了两种昆虫信息素(2S,5R)-2-甲基己内酯和(R)-十六烷的合成,
  • Synthesis of oxocenones from δ -lactones and their conversion to transposed oxocenes by a reductive ferrier reaction
    作者:Stuart L. Schreiber、Sarah E. Kelly
    DOI:10.1016/s0040-4039(01)90034-6
    日期:——
    The ring expansion of δ-lactones into oxocenones by the insertion of an acetylene is reported. A reductive Ferrier reaction can be employed to convert these products into transposed oxocenes.
    据报道,通过插入乙炔可将δ-内环扩展成环丁烯。可以采用还原性费里尔反应将这些产物转化为易位的茂属。
  • Versatile Copper-Catalyzed γ-C(sp3)–H Lactonization of Aliphatic Acids
    作者:Zhe Zhuang、Tao Sheng、Jennifer X. Qiao、Kap-Sun Yeung、Jin-Quan Yu
    DOI:10.1021/jacs.4c04043
    日期:2024.6.26
    carboxylic acids and cycloalkane acetic acids was observed, giving either fused or bridged γ-lactones that are difficult to access by other methods. δ-C–H lactonization was only favored in the presence of tertiary δ-C–H bonds. The synthetic utility of this methodology was demonstrated by the late-stage functionalization of amino acids, drug molecules, and natural products, as well as a two-step total synthesis
    位点选择性C(sp 3 )–H化在有机合成和药物发现中具有重要意义。游离羧酸的γ-C(sp 3 )–H内化提供了从丰富且廉价的羧酸制备具有生物学重要意义的内支架的最直接的方法;然而,具有广泛底物范围的这种转化的多功能催化剂仍然难以捉摸。在此,我们报道了一种简单但广泛适用且可扩展的游离脂肪酸γ-内化反应,该反应由催化剂与廉价的Selectflu作为化剂相结合实现。该内化反应表现出与叔键、苄基键、丙基键、亚甲基键和伯键 γ-C-H 键的相容性,可生成多种结构多样的内,例如螺内酯、稠合内和桥连内。值得注意的是,观察到环烷羧酸环烷乙酸的独特γ-亚甲基C-H内化,得到稠合或桥联的γ-内,这是其他方法难以获得的。仅当存在叔δ-C-H键时,才利于δ-C-H内化。该方法的合成效用通过氨基酸、药物分子和天然产物的后期功能化以及(异)薄荷内酯的两步全合成(迄今为止报道的最短合成)得到证明。
  • Cooperative Catalysis of Samarium Diiodide and Mercaptan in a Stereoselective One-Pot Transformation of 5-Oxopentanals into δ-Lactones
    作者:Jue-Liang Hsu、Chao-Tsen Chen、Jim-Min Fang
    DOI:10.1021/ol9911526
    日期:1999.12.1
    [GRAPHICS]We demonstrate a general method for conversion of various 5-oxopentanals to substituted delta-lactones and 1-oxa-2-decalones by the synergistic catalysis of samarium diiodide and 2-propanethiol (or disulfide), The deliberate use of mercaptan is advantageous to facilitate the catalytic cycle, This method shows high stereoselectivities, and an enantioselective procedure is feasible by using the chiral mercaptan (1R,2S)-1 phenyl-2-(N-acetamido)propanethiol as a promoter.
