【発明の名称】オスミウム触媒を用いるオレフィンの不斉ジヒドロキシル化法

Document Type and Number:

Japanese Patent JP2002543050

Kind Code:

A

Abstract:

This invention relates to process for asymmetric dihydroxylation of olefins using osmium catalysts to obtain monofunctional, bifunctional, and/or polyfunctional chiral 1,2-diols of the formula (I)where R1 to R4 are defined herein, by reacting an olefin of the formula (II)where R1 to R4 are defined as for formula (I),with molecular oxygen in the presence of an osmium compound and a chiral amine ligand in water or a water-containing solvent mixture at a pH of from 8.5 to 13.
