A process for the preparation of N-substituted 4-hydroxypiperidine, wherein an oxygen atom is inserted regioselectively into the corresponding N-substituted piperidine, by using as a biocatalyst a bacterium degrading alkanes or alicyclic hydrocarbons, or a prokaryotic host-organism having the gene(s) necessary for the hydroxylation derived from the said bacterium, or an enzyme having hydroxylation activity derived therefrom. The bacterium may be selected from species from, for example, the genera Sphingomonas and Pseudomonas, that are capable of degrading n-alkanes having 4 to 20 carbon atoms.
