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.

Pyrrolidine-oxyimides: new chiral catalysts for enantioselective Michael addition of ketones to nitroolefins in water
A new class of proline based organocatalysts 'pyrrolidine-oxyimides' were designed and synthesized from L-proline and hydroxyimides by employing a simple reaction protocol. These catalysts were found to be efficient in promoting asymmetric Michael additions of ketones to nitroolefins at room temperature. Good yields and high selectivities were obtained with catalyst 1a under additive-free conditions employing water as the reaction medium. (C) 2014 Elsevier Ltd. All rights reserved.
Cascade Oxa-Michael–Henry Reaction of Salicylaldehydes with Nitrostyrenes via Ball Milling: A Solvent-Free Synthesis of 3-Nitro-2H-chromenes
Cascade oxa-Michael-Henry reactions of salicylaldehyde derivatives with beta-nitrostyrenes catalyzed by potassium carbonate via solvent-free ball milling are demonstrated. The corresponding 3-nitro-2H-chromene products were obtained in moderate to excellent yields. This method offers significant advantages, particularly in terms of high yields, short reaction times and mild conditions.
