Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
154 words
A method for the production of the diastereomeric triazolyl alcohols of the formula ##STR5## where X is hydrogen, halogen, trifluoromethyl, C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy, unsubstituted or substituted phenyl or unsubstituted or substituted phenoxy wherein the substitute on the phenyl or the phenoxy is halogen and m is an integer from 1 to 5, x being identical or different when m is greater than 1, which, as diastereomers, have the R*,S* configuration at the two chiral centers, and the enantiomers which have the configuration R,S or S,R at the two chiral centers, and their acid addition salts and metal complexes, which comprises reducing stereo-selectively the corresponding ketone of the above formula with, (a) an alkyl magnesium halide which contains an alkyl radical of 2-6 carbon atoms and a beta-hydrogen atom in the alkyl radical or, (b) hydrogen in the presence of ruthenium or ruthenium oxide hydroxide (Ru(OH) x ).
Claim 2
Independent Claim
154 words
A method for the production of the diastereomeric triazolyl alcohols of the formula ##STR5## where X is hydrogen, halogen, trifluoromethyl, C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy, unsubstituted or substituted phenyl or unsubstituted or substituted phenoxy wherein the substitute on the phenyl or the phenoxy is halogen and m is an integer from 1 to 5, x being identical or different when m is greater than 1, which, as diastereomers, have the R*,S* configuration at the two chiral centers, and the enantiomers which have the configuration R,S or S,R at the two chiral centers, and their acid addition salts and metal complexes, which comprises reducing stereo-selectively the corresponding ketone of the above formula with, (a) an alkyl magnesium halide which contains an alkyl radical of 2-6 carbon atoms and a beta-hydrogen atom in the alkyl radical or, (b) hydrogen in the presence of ruthenium or ruthenium oxide hydroxide (Ru(OH) x ).
