  Synthesis of Alkylidenecyclopentenones and Dialkylidenecyclopentenones via the Coupling of Propargylic Alcohol and 2-Alkyne-1,4-diol Derivatives with Cyclopropylcarbene–Chromium Complexes

  摘要：

  The coupling of propargylic alcohols and their derivatives with cyclopropylcarbene-chromium complexes has been investigated. The coupling reaction leads to alkylidenecyclopentenones or alkoxyalkyl-cyclopentenones, depending on the leaving group ability of the propargyl substituent. A mechanism involving formation of a cyclopentadienone, followed by reduction and beta-elimination is proposed. Coupling of cyclopropylcarbene complexes with 2-alkyne-1,4-diol derivatives leads to dialkylidenecyclopentenone derivatives via a double elimination process. (C) 2000 Elsevier Science Ltd.

  Synthesis of aryl- and vinylacetylene derivatives by copper-catalyzed reaction of aryl and vinyl iodides with terminal alkynes

  摘要：

  The coupling reaction of aryl iodides with terminal alkynes by using a catalyst system of CuI-PPhs in the presence of K2CO3 as base gives the corresponding arylated alkynes in excellent yields. Addition of PPh3 is essential for the reaction to proceed catalytically. Vinyl iodides also react smoothly with the alkynes to give enyne compounds with retention of the configurations. While DMF and DMSO can be used as solvents, DMSO is found to be effective for the reaction with aliphatic terminal alkynes. A reaction mechanism involving initial formation of copper acetylide species coordinated by PPh3 followed by reaction of aryl and vinyl iodides is proposed.

• Benzannulation of Substituted 3-Alkoxycarbonylhex-3-en-5-ynoic Acids: A New Route to 4-Substituted 3,5-Dihydroxybenzoic Acids Derivatives
  作者：Stefano Serra、Claudio Fuganti

  DOI：10.1055/s-2002-34212

  日期：——

  A new regioselective pathway to 4-substituted 3,5-dihydroxybenzoic acids derivatives is described here. According to this procedure substituted propargylic aldehydes are converted into substituted 3-alkoxycarbonylhex-3-en-5-ynoic acids, which are in turn, treated with acetic anhydride in the presence of sodium acetate to give the substituted benzoic acids derivatives. The aromatic moiety constructed

  A tunable rhodium‐catalyzed intramolecular alkyne insertion reaction proceeding through the CC cleavage of benzocyclobutenones is described. Selective formation of either the direct or decarbonylative insertion product can be controlled by using different catalytic systems. A variety of fused β‐naphthol and indene scaffolds were obtained in good yields with high functional group tolerance. This work

  Through the use of [PdCl(C3H5)]2/cis,cis,cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane as catalyst, a range of vinyl bromides undergoes Sonogashira cross-coupling reaction with a variety of alkynes, leading to the corresponding 1,3-enynes in good yields. The reaction tolerates several alkynes such as phenylacetylene, dec-1-yne, 2-methylbut-1-en-3-yne a range of alk-1-ynols, 3,3-diethoxyprop-1-yne

  A CoCl2·6H2O/Zn reagent using 2-(2,6-diisopropylphenyl)iminomethylpyridine (dipimp), 1,2-bis(diphenylphosphino)ethane (dppe), or 1,2-bis(diphenylphosphino)benzene (dppPh) as a ligand effectively catalyzed the cross-addition reaction of silylacetylene to internal alkynes. The reaction of some unsymmetrical internal alkynes, such as 3-arylpropargyl alcohols, proceeded in a highly regioselective manner

  使用2-（2,6-二异丙基苯基）亚氨基甲基吡啶（dipimp），1,2-双（二苯基膦基）乙烷（dppe）或1,2-双（二苯基膦基）苯（dppPh）的CoCl 2 ·6H 2 O / Zn试剂）作为配体有效地催化了甲硅烷基乙炔与内部炔烃的交叉加成反应。一些不对称内部炔烃（例如3-芳基炔丙醇）的反应在dppe或dppPh的存在下以高度区域选择性的方式进行，但在dipimp的存在下产生了近1：1的区域异构体混合物。使用1-氘代2-甲硅烷基乙炔的反应结果表明，该反应涉及甲硅烷基乙炔C–H键与钴的直接氧化加成。
