  • Studies of bioactive heterocycles: facile thio-Claisen rearrangement of propargylthio[1]benzopyran-2-ones
    作者:K.C Majumdar、S.K Ghosh
    DOI:10.1016/s0040-4039(02)00195-8
    日期:2002.3
    Hitherto unreported 2H-thiopyrano[3,2-c][1]benzopyran-5-ones 6a–f are synthesized regioselectively in 79–85% yields by the thio-Claisen rearrangement of 4-propargylthio[1]benzopyran-2-ones 5a–f. The substrates 5a–f are synthesized by alkylation of hitherto unreported 4-mercaptocoumarins.

  • N-Heterocyclic Carbene Derived Nickel-Pincer Complexes: Efficient and Applicable Catalysts for Suzuki-Miyaura Coupling Reactions of Aryl/Alkenyl Tosylates and Mesylates
    作者:Jun-ichi Kuroda、Kiyofumi Inamoto、Kou Hiroya、Takayuki Doi
    DOI:10.1002/ejoc.200900067
    日期:2009.5
    activities of NHC-derived nickel–pincer complexes for the Suzuki–Miyaura coupling reactions of aryl/alkenyl tosylates and mesylates are described. In the presence of a catalytic amount of nickelacycle 1a, a wide array of tosylates and mesylates reacted with several aryl- and alkenylboronic acids to afford the coupling products, generally in high yields. Fine tuning of the reaction conditions for each class
    描述了 NHC 衍生的镍钳配合物对芳基/烯基甲苯磺酸酯和甲磺酸酯的 Suzuki-Miyaura 偶联反应的催化活性。在催化量的镍环 1a 存在下,多种甲苯磺酸盐和甲磺酸盐与几种芳基硼酸和烯基硼酸反应得到偶联产物,通常产率很高。只有通过选择合适的反应介质(甲苯磺酸盐为 DME,甲磺酸盐为二恶烷),才能对每类亲电子​​试剂的反应条件进行微调。(© Wiley-VCH Verlag GmbH & Co. KGaA,69451 Weinheim,德国,2009)

  • Facile synthesis of 4-acetyl-coumarins, -thiocoumarin and -quinolin-2(1H)-one via very high α-regioselective Heck coupling on tosylates
    作者:Sergio Valente、Gilbert Kirsch
    DOI:10.1016/j.tetlet.2011.04.033
    日期:2011.7
    An efficient synthesis of a series of methyl ketones at the C4 position of coumarins, coumarin-containing heterocycles and analogous scaffolds is reported via very high α-regioselective Heck coupling using tosylates and in very high yields. Although α-regioselectivity in Heck coupling can be obtained with triflates as substrates, tosylates are less toxic, less expensive and, importantly, more stable
    据报道,通过使用甲苯磺酸盐的非常高的α-区域选择性Heck偶联,并以非常高的收率,在香豆素,含香豆素的杂环和类似支架的C4位有效合成了一系列甲基酮。尽管可以用三氟甲磺酸酯作为底物获得Heck偶联中的α-区域选择性,但是甲苯磺酸盐的毒性较小,价格较低并且重要的是更稳定。
