  • One-Step Synthesis of Isocoumarins and 3-Benzylidenephthalides via Ligandless Pd-Catalyzed Oxidative Coupling of Benzoic Acids and Vinylarenes
    作者:Debkumar Nandi、Debalina Ghosh、Shih-Ji Chen、Bing-Chiuan Kuo、Nancy M. Wang、Hon Man Lee

    日期:2013.4.5
    A straightforward synthetic method for the preparation of isocoumarins and 3-benzylidenephthalides via C–H olefination and oxidative coupling of readily available benzoic acids and vinylarenes was developed. The directing effect of the substituents on the benzoic acid allows for the synthesis of both types of lactone in pure form.

    phthalides is presented. The reaction is carried out in molten tetrabutylammonium acetate (ionic liquid) which allows the use of an amount of palladium acetate from ten to twenty times lower than that of similar protocols in molecular solvents (0.5 % mol). Oxygen is used as a reoxidant for the metal, mediated by copper acetate.

    日期:1998.7.1
    N-(2'-Phenylphenyl)benzenesulfonamides react with acrylate esters accompanied via cleavage of the C-H bond at their 2'-position in the presence of a catalyst system of Pd(OAc)(2) and Cu(OAc)(2) and a base under air to produce 5,6-dihydro-5-(benzenesulfonyl)phenanthridine-6-acetate derivatives in high yields. The reactions of benzoic acid with butyl acrylate and styrene can also give 3-[(butoxycarbonyl)methyl]phthalide and 3-phenylisocoumarin, respectively.

  • Rhodium-Catalyzed Oxidative Coupling of Benzoic Acids with Terminal Alkynes: An Efficient Access to 3-Ylidenephthalides
    作者:Yang Liu、Yudong Yang、Yang Shi、Xiaojie Wang、Luoqiang Zhang、Yangyang Cheng、Jingsong You

    日期:2016.5.23
    Herein we disclose the first example of transition-metal-catalyzed oxidative coupling/annulation of simple benzoic acids with terminal alkynes via C-H activation. A range of aromatic carboxylic acids and terminal alkynes have been found to be viable substrates in this reaction, providing a simple and efficient method for the synthesis of diverse 3-ylidenephthalides with complete Z selectivity.
