    摘要:
    本文介绍了在离子液体介质(BmimBF4)中通过 2-(1-羟基丙-2-炔基)苯酚 1 的杂环合成 2-亚甲基-2,3-二氢苯并呋喃-3-醇 2 的可循环钯催化合成方法。该过程是在相对温和的条件下(100 °C,5 小时),在催化量(2 摩尔%)的 PdI2 与 KI(相对于 PdI2 为 5 等份)和有机碱(如吗啉,相对于 1 为 1 等份)的存在下进行的,从而得到高产率(70%-86%)的 2。PdI2-KI 催化系统可循环使用多达六次,而不会明显丧失活性。此外,通过酸催化的烯丙基异构化或烯丙基亲核取代,产物 2 可以很容易地以一锅方式转化为 2-羟甲基苯并呋喃 3(52%-71%,以 1 为基准)和 2-甲氧基甲基苯并呋喃 4(52%-80%,以 1 为基准)。

    A Novel Palladium-Catalyzed Dicarbonylation Process Leading to Coumarins
    摘要:
    [GRAPHICS]A novel approach to coumarin derivatives has been developed starting from readily available 2-(1-hydroxyprop-2-ynyl)phenols, based on an unprecedented palladium-catalyzed dicarbonylation process. Reactions were carried out in the presence of catalytic amounts of PdI2 in conjunction with an excess of KI in MeOH as the solvent at room temperature and under 90 atm of CO to give 3-[(methoxycarbonyl)-methyl]coumarins in good to high isolated yields (62-87%).

    A recyclable palladium-catalyzed synthesis of 2-methylene-2,3-dihydrobenzofuran-3-ols 2 by heterocyclization of 2-(1-hydroxyprop-2-ynyl)phenols 1 in an ionic liquid medium (BmimBF4) is presented. The process takes place under relatively mild conditions (100 °C, 5 h) in the presence of catalytic amounts (2 mol %) of PdI2 in conjunction with KI (5 equiv with respect to PdI2) and an organic base, such as morpholine (1 equiv with respect to 1), to give 2 in high yields (70%–86%). The PdI2-KI catalytic system could be recycled up to six times without appreciable loss of activity. Moreover, products 2 could be easily converted in a one-pot fashion into 2-hydroxymethylbenzofurans 3 (52%–71%, based on 1) and 2-methoxymethylbenzofurans 4 (52%–80%, based on 1) by acid-catalyzed allylic isomerization or allylic nucleophilic substitution.
