heal.abstract	Novel functionalized organo-morganic chiral catalysts have been prepared in two steps from activated silica gel and chiral organic auxiliaries, such as (+)-cinchonine or (S)-(-)-nicotine. These new catalysts have been tested in a solid-liquid-liquid three-phase system for the asymmetric epoxidation of alpha,beta-enones and the asymmetric alkylation reactions of glycine derivatives. The obtained stereoselectivities are negligible for the first case (ee < 2%) and appreciable (ee 25-55%) for the second one. (c) 2007 Elsevier B.V. All rights reserved.	en
