Abstract (en)
[origin: WO0012745A1] The invention relates to a method for preparing (R)-piperidine derivatives of the general formulas (I) and (VII), where R<1> is hydroxy, amino or C1-6-alkoxy and R<4> is hydroxy or amino. Said (R)-piperidine derivatives are obtained from (RS)-piperidine derivatives of the general formula (II), in which R<2> is hydroxy, amino or C1-6-alkoxy, in the presence of trace elements and using micro-organisms or cell-free enzymes from said micro-organisms.
