  Abstract Amberlyst 15 resin supported the tandem reaction of cinnamic acids with phenols under solvent-free reaction condition has been introduced to afford 4-aryl-3,4-dihydrocoumarin (neoflavanone) derivatives. The efficiency of solid acidic sulfonic resin (A-15) has been illustrated in two reaction activation methods such as microwave irradiation and conventional heating. The important roles of Amberlyst

  摘要 Amberlyst 15 树脂支持肉桂酸与酚类在无溶剂反应条件下的串联反应，得到 4-芳基-3,4-二氢香豆素（新黄烷酮）衍生物。固体酸性磺酸树脂 (A-15) 的效率已通过微波辐射和常规加热两种反应活化方法进行了说明。Amberlyst 15 的重要作用通过在微波辐射的辅助下比常规加热在更短的时间内产生高产率 4-芳基-3,4-二氢香豆素，以及其六次催化剂运行的高回收率和可重复使用性而得到强烈强调。通过XRD和FE-SEM对原始催化剂和回收催化剂进行表征，以研究再利用催化剂的表面与其可回收性的相关性。

  Molecular iodine was used as a catalyst in the [3+3] cyclocoupling of phenols and cinnamic acids which proceeds via a tandem esterification–hydroarylation process at 120–130 °C under solvent-free conditions. Substituted 4-aryl-3,4-dihydrobenzopyran-2-ones were obtained in good yields.

  The first palladium-catalyzed asymmetric addition of arylboronic acids to coumarins was successfully established, providing a straightforward asymmetric approach to achieving pharmaceutically important 4-aryl-3,4-dihydrocoumarins. This methodology features easily accessible and bench-stable ligands, a wide substrate scope, mild conditions, and accommodation of electron-withdrawing arylboronic acids

  A facile approach has been developed for the synthesis of dihydrocoumarin derivatives through the reaction of phenols and cinnamoyl chloride in the presence of ecofriendly solid-acid catalyst montmorillonite K-10 via a tandem esterification-Friedel-Crafts alkylation process under microwave irradiation. The catalyst could be easily recovered and recycled.

  Molecular iodine as an inexpensive catalyst is described in the construction of 2-substituted or 2,2-disubstituted chromans and 4-aryl-3,4-dihydrobenzopyran-2-ones via [3+3] cyclocoupling. For the synthesis of chromans, phenols and allylic alcohols were refluxed in chloroform in presence of 20 mol % I-2 while [3+3] cyclocoupling of phenols and cinnamic acids proceeded to give 4-aryl-3,4-dihydrobenzopyran-2-ones using 30 mol % I-2. Later reaction occurs via a tandem hydroarylation-esterification process at 120-130 degrees C under solvent free conditions. Chromans were obtained in 20-92% yields and substituted 4-aryl-3,4-dihydrobenzopyran-2-ones were obtained in 5-85% yields. (C) 2014 Elsevier Ltd. All rights reserved.
