PREPARATION OF OPTICALLY ACTIVE 1-ALKOXY OR ARYLOXY-2-ALKANOL COMPOUNDS

摘要

The invention concerns a method for optically preparing 1-alkoxy or aryloxy-2-alkanol compounds by asymmetric hydrogenation of unsaturated compounds of formula (IV) wherein: R and R' are the same as in formula (I) wherein: R represents a C1-C6 aryl, aryl-alkyl or alkyl group, optionally substituted by a C1-C4 alkyl group, an alkoxy or a halogen atom, in the presence of a ruthenium-based catalyst.
