PROCESS FOR PREPARING (R OR S)-2-ALKYL-3-HETEROCYCLYL-1-PROPANOLS
Compounds of the formula (I) in which R’1, R’2,R’3 and Het are each defined as specified in the description are obtainable in high yields by a stereoselective addition of R’3-substituted propionic esters onto R’1- and R’2-substituted unsaturated, bicyclic heterocyclylaldehydes of the formula R-CHO to give corresponding 3-(R)-3-hydroxy-2-R’3-propionic esters. Conversion of the OH group to a leaving group, a subsequent regioselective elimination to give 3-(R)-2-R’3-propenoic esters, followed by: 1) hydrolysis to the corresponding 3-(R)-2-R’3-propenoic acids, their enantioselective hydrogenation to corresponding chiral 3-(R)-2-R’3-propenoic acids and their reduction, or 2) hydrolysis to the corresponding 3-(R)-2-R’3-propenoic acids, their reduction to corresponding 3-(R)-2-R’3-allylalcohols and their enantioselective hydrogenation, or 3) reduction to corresponding 3-(R)-2-R’3-allylalcohols and their enantioselective hydrogenation, where R is formula (II) and the enantioselective hydrogenations are performed with metal complexes which have, as ligands, ferrocene-1,1′-diphosphines which have, in the 1-position, a ferrocene-substituted secondary phosphine group and, in the1′-position, a secondary phosphine group.
