Oxidative [3+3] Annulation of Atropaldehyde Acetals with 1,3-Bisnucleophiles: An Efficient Method of Constructing Six-Membered Aromatic Rings, Including Salicylates and Carbazoles
An oxidative [3+3] annulation of atropaldehyde acetals with various 1,3-bisnucleophiles was developed using either N-bromosuccinimide or copper(II) bromide as oxidizing reagent and Br¡ãnsted or Lewis acids as catalyst. The [3+3] annulations can be considered mechanistically as oxidizing reagent-induced acid-acid-catalyzed domino reactions established through the concept of auto-tandem catalysis. Alkyl acetoacetates, alpha-(indol-2-yl)acetate, anilines, 1-methyl-1H-pyrazol-3-amine, ethyl 5-amino-1H-pyrazole-3-carboxylate, and 3-amino-1H-indazole can all be used as 1,3-bisnucleophiles in this type of transformation. The established reactions can very efficiently construct six-membered aromatic rings, including salicylates and carbazoles. A four-step method of synthesizing the anti-inflammatory agent diflunisal was also developed based on the oxidative [3+3] annulation reaction, and the yield was high. (Figure presented.).
Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about is helpful to your research. Recommanded Product: 33588-64-6
