  An Efficient Synthesis of 2-Quinoxalinecarboxylic Acid

  摘要：

  Development of a cost efficient and scaleable process for 2-quinoxalinecarboxylic acid is described. The primarily goals of the development work were to improve the overall yield of the process, to minimize the use of environmentally unacceptable materials, and to obtain a material with a high level of purity. A variety of approaches were examined, and the most efficient method was a condensation of o-phenylenediamine with a monosaccharide followed by a mild peroxide oxidation.

  chiral Ir/H8‐binapo catalyst exhibits unprecedented reactivity and excellent enantioselectivity in the hydrogenation of quinoxalines at a high ratio of substrate to catalyst (from 100 to 20 000). This new method provides a practical synthetic approach to give optically active chiral tetrahydroquinoxaline derivatives (see scheme; cod=1,5‐cyclooctadiene).

  A general asymmetric hydrogenation of a wide range of 2-alkyl- and 2-aryl-substituted quinoxaline derivatives catalyzed by an iridium–difluorphos complex has been developed. Under mild reaction conditions, the corresponding biologically relevant 2-substituted-1,2,3,4-tetrahydroquinoxaline units were obtained in high yields and good to excellent enantioselectivities up to 95%. With a catalyst ratio

• pH-Regulated transfer hydrogenation of quinoxalines with a Cp*Ir–diamine catalyst in aqueous media

  The combination of [Cp*IrCl2](2) with N-(2-aminoethyl)-4-(trifluoromethyl)benzenesulfonamide constitutes an efficient catalyst for selective transfer hydrogenation of a variety of quinoxalines in water with HCOONa as the hydrogen source, affording the corresponding tetrahydroquinoxalines in good to excellent yields. The catalyst is air-stable, and the reduction could be performed without nitrogen protection. The aqueous phase reduction is shown to be highly pH-dependent, with acidic pH leading to better results. There exits a pH window for optimum rate, and the use of HOAc/NaOAc buffer solution is essential for maintaining a stable pH during the reaction. (C) 2011 Elsevier Ltd. All rights reserved.
