  摘要：

  通过使用具有2,2'-联吡啶的非手性配体的铜催化剂，可以实现与α-（2-卤代苯甲酰基氨基）苄基硼酸酯的对映体分子内Suzuki-Miyaura型偶联，生成3-取代的异吲哚啉酮。在具有高对映体特异性的6-苯基-2,2'-联吡啶配体的存在下，在硼结合的立体碳上带有氢原子的对映体富集的α-氨基苄基硼反应物进行立体反转偶联。在存在简单的2,2'-联吡啶作为配体的情况下，带有完全取代的与硼结合的立体成核中心的α-氨基苄基硼酸酯也给出了3,3-二取代的异吲哚啉酮，具有立体定向的立体化学转化作用。

  锌催化的对映选择性和非对映选择性形式 [4 + 2] 环加成，涉及两个缺电子伙伴：1-氮杂二烯和硝基烯烃不对称合成哌啶

  摘要：

  我们报告了通过 1-氮杂二烯和硝基烯烃的 [4 + 2] 环加成反应催化不对称合成哌啶。该反应使用地球上丰富的锌作为催化剂，并且具有高度的非对映选择性和区域选择性。一种新型 BOPA 配体 (F-BOPA) 在该过程中具有高反应性和对映选择性。发现与双（恶唑啉）相邻的芳烃上存在邻位取代特别有影响，因为限制了 1-氮杂二烯与路易斯酸的不希望的配位，从而允许反应在较低温度下进行。使用一系列配体进行的一系列次级动力学同位素效应研究暗示了转化的逐步机制，包括亚胺与硝基烯烃的初始迈克尔型加成，然后是环化事件。

  Reaction of isonitriles with 3‐(arylamino)isobenzofuran‐1(3H)‐ones in the presence of a catalytic amount of an octahydro (R)‐binol‐derived chiral phosphoric acid afforded 3‐oxo‐2‐arylisoindoline‐1‐carboxamides in high yields with good to high enantioselectivities. An enantioselective Ugi four‐center three‐component reaction of 2‐formylbenzoic acids, anilines, and isonitriles was subsequently developed

  在催化量的八氢（R）-苯酚衍生的手性磷酸存在下，异腈与3-（芳基氨基）异苯并呋喃-1（3 H）-酮反应，得到3-氧代-2-芳基异吲哚啉-1-羧酰胺高收率，对映选择性好。随后开发了2-甲酰基苯甲酸，苯胺和异腈的对映选择性Ugi四中心三组分反应，用于合成相同的杂环。机理研究表明，对映选择性是由主要的Ugi加合物的动态动力学拆分引起的，而不是由C-C键形成过程引起的。所得的杂环产物具有重要的医学重要性。
