  Readily available and recoverable chiral ionic phosphite ligands for the highly enantioselective hydrogenation of functionalized olefins

  摘要：

  A series of novel ionic phosphite ligands bearing carbohydrate groups were conveniently synthesized and successfully applied in the asymmetric hydrogenation of enamides, alpha-dehydroamino acid esters, and dimethyl itaconate. High efficiency and excellent reusability were obtained in an ionic liquid-toluene biphasic system. (C) 2011 Elsevier Ltd. All rights reserved.
