摘要
New sugar amide-pyrrolidine derivatives possessing the furano form of the carbohydrate template were designed and developed as efficient and stereoselective organocatalysts for asymmetric Michael additions of ketones to nitroolefins at room temperature. Good yields and high selectivities were achieved with catalyst 2 under solvent-free and additive-free reaction conditions. (C) 2014 Elsevier Ltd. All rights reserved.
