Abstract

Osmium-catalyzed asymmetric dihydroxylation of olefins provides one of the most elegant methods for the preparation of chiral vicinal diols. 1 Although the reactions could be applied to the synthesis of pharmaceuticals, fine chemicals, and so forth, the high cost, toxicity, and possible contamination of osmium catalysts in the products restrict its use in industry. Heterogenization of the ligands on polymer or silica gel support and eventual ...
