In homogeneous catalysis, catalysts are in the same phase as the reactants. Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 86-99-7, Name is 7-Chloroquinolin-4-ol, molecular formula is C9H6ClNO, belongs to quinoxaline compound, is a common compound. In a patnet, author is Xiang, Yunyu, once mentioned the new application about 86-99-7, Safety of 7-Chloroquinolin-4-ol.
Copper-mediated formal [5+1] annulation of 2-vinylanilines and glyoxylic acid: A facile approach for the synthesis of 4-arylated quinolines
A copper-mediated formal [5 + 1] oxidative annulation of 2-vinylanilines and glyoxylic acid to 4-arylated quinolines was developed. A series of 4-arylated quinoline derivatives were obtained in good to excellent yields. This protocol could be carried out efficiently on gram scale. The transformation probably underwent nucleophilic addition/6 pi electrocyclization/oxidative aromatization and the elimination of CO2 cascade processes. (C) 2020 Elsevier Ltd. All rights reserved.
