Method of preparing (S)- or (R) -3,3,3-trifluoro-2-hydroxy-2-methylpropionic acid |
摘要 |
Described are new micro-organisms and a new enzyme capable of using as sole source of nitrogen the propionic acid amide of formula (VI), in racemate form or as optically active isomers. Described also is a method of preparing (S)- or (R)-3,3,2-trifluoro-2-hydroxy-2-methylpropionic acid of formulas (I) and (II) starting from trifluoroaceto-acetic ester. The first three process steps are chemical, the fourth process step microbiological.
