Synthesis of Imidazoles and Oxazoles via a Palladium-Catalyzed Decarboxylative Addition/Cyclization Reaction Sequence of Aromatic Carboxylic Acids with Functionalized Aliphatic Nitriles
We herein report an efficient approach for the assembly of multiply substituted imidazoles and oxazoles in a single-step manner. These transformations are based on a decarboxylation addition and annulation of readily accessible aromatic carboxylic acids a
The reactions of benzoyl fluorides (p-Me2N, p-MeO, m-Cl) with primary amines of pKa = 3.9-11 in aqueous solution follow a first-order dependence on amine concentration and the addition of 0.83 M potassium phosphate, 10percent dianion, does not
