  • Manganese‐Catalysed C−H Activation: A Regioselective C−H Alkenylation of Indoles and other (hetero)aromatics with 4‐Hydroxy‐2‐Alkynoates Leading to Concomitant Lactonization
    作者:Anil Kumar、Nachimuthu Muniraj、Kandikere Ramaiah Prabhu
    DOI:10.1002/adsc.201900678
    日期:2019.11.5
    A manganese‐catalyzed C−H bond alkenylation of indoles at C2‐position with 4hydroxy2alkynoates leading to concomitant lactonization under removable directing group strategy has been disclosed. This lactonization strategy exhibits regioselectivity, a broad substrate scope, and a good functional group tolerance furnishing the products in low to high yields. The regioselectivity is guided by the electronic
    已经公开了在4-位-2-羟基的链烷酸酯在C2-位的吲哚催化的CH键链烯基化,从而在可移动的导向基团策略下导致伴随的内酯化。这种内酯化策略显示出区域选择性,广泛的底物范围和良好的官能团耐受性,从而以低到高收率提供了产品。区域选择性受酯基团的电子效应以及4-羟基-2-链烷酸酯的C4位的空间体积的影响。反应后,直接除去了导向基团以获得不含NH的吲哚

    日期:2020.3.6
    A Rh(III)-catalyzed cascade C-H activation; regioselective [4 + 2] oxidative annulation; and lactonization of aromatic acids, anhydrides, and acrylic acid derivatives with 4-hydroxy-2-alkynoates have been disclosed. This strategy leads to fused heterocyclic lactone scaffolds in a single step with moderate functional group tolerance and excellent site selectivity. Besides, in one step, an antipode of

    日期:2024.9
    The rhodium-catalyzed CH bond activation and cyclization of 3-oxopent-4-enenitriles with alkynes proceed efficiently. Various 2H-pyrans with multiple substituents are achieved in good yields through regioselective formation of C—O and CC bonds. Transformations involving hydroxy-alkynoates resulted in products with a furo[3,4-b]pyran skeleton via further intramolecular ester exchange processes. Different
