  二氢萘并呋喃和二氢苯并呋喃的有机催化对映选择性合成：反应发展和对立体选择性的洞察

  Squaramide/金鸡纳生物碱衍生的双功能有机催化剂在不对称转化中有很高的需求。双功能奎宁衍生的空间阻碍角酰胺（H 键供体）有机催化剂用于催化不对称 Friedel–Crafts/S N 2 型多米诺反应 ( Z)-α-溴硝基烯烃和 α/β-萘酚和苯酚衍生物，分别生成对映体富集的二氢萘并呋喃 (DHN) 和二氢苯并呋喃 (DHB) 衍生物。与文献中已知的方法相比，在温和条件下以相对较低的催化剂负载量 (5 mol%) 获得了高达 >99% ee 的目标加合物。此外，还进行了密度泛函理论 (DFT) 计算以确定可能的结果，解释了立体选择性的起源。据发现，Friedel-Crafts 步骤中反式构象的 π 堆叠相互作用比顺式构象稳定 0.79 kcal mol -1。

  硼酸-胺双功能化聚丙烯腈纤维协同催化亨利反应

  摘要：

  本文采用酸碱配对和制备方法构建酸碱双功能多相催化剂。通过形成酰胺键将硼酸基团引入伯胺官能化聚丙烯腈纤维（PAN EA F）中，以 PAN EA F 的氨基 N 原子为锚定点，制备硼酸-胺双官能 PANF 作为可回收的多相催化剂。如此获得的分别含有连接在苯环和吡啶环上的硼酸基团的纤维催化剂PAN EA-BA1 F和PAN EA-BA2 F，分别用于芳基醛与硝基甲烷的亨利反应。催化研究表明其性能与硼酸的变化有很大的相关性。平底锅EA-BA2 F 表现出比 PAN EA-BA1 F更高的底物选择性，并且只有具有羟基、二甲氨基和酰胺基团的苯甲醛才具有反应性，初步表现出类似酶催化的底物特异性。以环十二烷为溶剂，通过拉曼和傅里叶变换红外光谱（FT-IR）分析进行原位研究，以阐明催化差异。此外，还解释了苯甲醛在 PAN EA-BA1 F 催化缩合反应中不常见的逆反应顺序。
