In this paper we present new, monodentate phosphoramidite ligands based on amines derived from the easy available monosaccharide d-xylose and BINOLs. Ligands were used for copper-catalyzed conjugate addition to acyclic and cyclic enones. The highest enantioselectivity achieved in this study was 77% ee for the conjugate addition to trans-chalcone, which is comparable to the best results published to date for phosphoramidite ligands based on carbohydrate-derived amines.

α-Aminonitriles have been stereoselectively introduced at non-anomeric positions of monosaccharides, in which the carbon C-α is one of the atoms of the sugar ring. Target compounds were prepared from various ulose derivatives and amines using titanium(IV) isopropoxide as a mild and effective Lewis acid. (C) 2000 Elsevier Science Ltd.
