Process for the preparation of (-)-(2R,3S)-2,3-epoxy-3-(4-methoxyphenyl)methylpropionate |
| abstract |
In a starting mixture containing the dextrorotatory and levorotatory enantiomers of methyl trans-2,3-epoxy-3-(4-methoxyphenyl)propionate, the dextrorotatory enantiomer is subjected to transesterification in an anhydrous medium, which converts it to an insoluble derivative, in the presence of an enzyme which does not affect the levorotatory enantiomer. The latter is a synthetic intermediate of compounds such as Diltiazem. |
