  摘要：

  一种高效合成新型官能化的2-芳基-4-(吲哚-3-基)-4H-香豆素的方法被开发，该方法在催化剂碘的存在下，从易得的起始材料2-羟基查尔酮衍生物合成。吲哚、取代吲哚和7-氮杂吲哚适合这种转化。提出了可能的多米诺迈克尔加成-分子内环化反应机制。

  deliver structurally diverse hybrid flavonoids in good to excellent yields in the presence of a catalytic Brønsted acid. Moreover, moderate enantioselectivities could be obtained using a catalytic chiral phosphoric acid via counter anion directed addition. Based on mechanistic studies, the reaction is proposed to proceed via tandem double-bond isomerization/dehydrated cyclization of 2-hydroxychalcone

  描述了一种由 2-羟基查耳酮合成的杂合类黄酮的仿生合成。在 24 W CFL 的照射下，2-羟基查耳酮与各种亲核试剂反应，在催化布朗斯台德酸存在下以良好至优异的产率提供结构多样的杂化黄酮类化合物。此外，使用催化手性磷酸通过反阴离子定向加成可以获得中等的对映选择性。基于机理研究，该反应被提议通过2-羟基查耳酮的串联双键异构化/脱水环化形成瞬时黄鎓阳离子，该阳离子被亲核试剂原位捕获以提供杂化黄酮类化合物。

  2-Methylindole was used as an indicative nucleophile for rapid screening of MCRs of aldehydes with two different nucleophiles. By removal of some samples that have characteristic color associated with the generation of di(indolyOmethane derivatives the difficulties encountered in the product analysis were alleviated significantly.

  An efficient synthesis of novel functionalized 2-aryl-4-(indol-3-yl)-4H-chromenes has been developed, in the presence of a catalytic amount of iodine, from easily available starting materials, 2-hydroxychalcone derivatives. Indole, substituted indoles and 7-azaindole are suitable for this transformation. The possible domino Michael addition–intramolecular cyclization reaction mechanism is proposed.
