    摘要: The invention relates to a biotechnological method for producing trifluoro-3(R)-hydroxybutyric acid derivatives of the general formula (I), where R1 represents —OR2, where R2 is hydrogen, C1-10 alkyl, C1-10 alkenyl, C3-8 cy-cloalkyl, aryl, alkoxyalkyl or alkoxyalkoxyalkyl; —NR3R4, where R3 and R4 are the same or different and represent hydrogen, C1-10 alkyl, C1-10 alkenyl, C3-8 cycloalkyl or aryl; or —SR5, where R5 represents hydrogen, C1-10 alkyl, C1-10 alkenyl, aryl or C3-8 cycloalkyl, based on a trifluoroacetoacetic acid derivative of the general formula (II), where R1 has the meaning given above, by means of micro-organisms which are able to reduce a carbonyl function or by means of a cell-free enzyme extract of said micro-organisms.
