| titleOfInvention | Process for the preparation of enantiomerically pure flavanones |
| abstract | Process for the preparation of a (2S) - or (2R) -flavanone with the steps: a) Reduction of a racemic mixture of a flavanone of the general formula rac-1: wherein R 1 and R 2 are selected from H, alkyl and halogen, wherein R 3 and R 5 are selected from alkyl and acyl, wherein R 4 is selected from H, alkyl and acyl, wherein each alkyl is selected from unsubstituted or substituted, saturated or unsaturated, straight-chain or branched alkyl groups having 1 to 15 carbon atoms and acyl is in each case selected from unsubstituted or substituted, saturated or unsaturated, straight-chain or branched acyl groups having 1 to 10 carbon atoms, with a mixture of formic acid and a base, in the presence of a chiral catalyst of the general formula: including: A central metal M selected from rhodium (III), ruthenium (II) or iridium (III), A π-ligand A of the general formula: wherein R 5 and R 6 are selected from alkyl and unsubstituted or substituted ... |
