  • Electrocyclization of cis-dienals in organic synthesis: a new and versatile synthetic method for the preparation of aryl- and heteroaryl-fused coumarins
    作者:Yung-Son Hon、Tze-Wei Tseng、Chia-Yi Cheng
    DOI:10.1039/b912887e
    日期:——
    Benzo-, furo-, thieno-, and pyrido[f]coumarins were prepared by generating the 2H-pyran-2-one moieties from the oxidation of the corresponding 2H-pyran rings, which were formed in situ from the electrocyclization of cis-dienals.

    日期:——
    coumarin derivatives via a tandem double bond isomerization/oxidative cyclization of cinnamic acids. Inexpensive and stable xanthone was used as the photocatalyst, and readily available Selectfluor was used as the oxidant. This method tolerates a wide range of functional groups and offers excellent chemical yields in general. Besides, the photocatalytic oxidative cyclization of cinnamic acid esters gives

  • Lewis acid-catalyzed annulative partial dimerization of 3-aryloxyacrylates to 4-arylchroman-2-ones: synthesis of analogues of tolterodine, RORγ inhibitors and a GPR40 agonist
    作者:Rupesh A. Kunkalkar、Rodney A. Fernandes
    DOI:10.1039/c8cc09785b
    日期:——
    annulative partial dimerization of 3-aryloxyacrylates to 4-arylchroman-2-ones catalyzed by Lewis acid (BF3·OEt2) has been developed. The reaction involves two molecules of 3-aryloxyacrylate, resulting in the loss of one propiolate molecule to furnish 4-arylchroman-2-one, an important structural motif found in many natural products. This methodology has been elaborated to synthesize analogues of tolterodine

  • A General Synthetic Route to Dibenzospiropyrans and Dinaphthospiropyrans from Dibenzofuran and Dinaphthofuran
    作者:Baiquan Wang、Bin Wang、Minxiong Li、Shansheng Xu、Haibin Song
    DOI:10.1055/s-2007-966061
    日期:2007.6
    The reaction of dibenzofuran or dinaphthofuran with lithium in anhydrous diethyl ether led to a solution of the corresponding C,O-dilithiated intermediate which, upon treatment with 1,3,3-trimethylindolin-2-one or different coumarin derivatives at -78 °C, afforded, after hydrolysis, dibenzospiropyrans and dinaphthospiropyrans in good yields. The structures of all new compounds were determined by single crystal X-ray analysis.
    在无水二乙醚中,二苯并呋喃或二萘并呋喃与锂反应生成相应的C,O-二锂化中间体,该中间体经与1,3,3-三甲基吲哚啉-2-酮或不同香豆素衍生物在-78°C下处理后,经水解得到高产率的二苯并螺吡喃和二萘并螺吡喃。所有新化合物的结构均通过单晶X射线分析确定。
