Process for the preparation of N-hydroxyalkyl-substituted 3,4,5-trihydroxypiperidine derivatives

摘要

The present invention relates to a process for the preparation of N-hydroxyalkyl-substituted 3,4,5-trihydroxypiperidine derivatives of the formula I <IMAGE> in which n represents 1 or 2 and R radicals in each case independently from one another denote hydrogen or an optionally substituted, straight-chain, branched or cyclic, saturated or unsaturated radical or an optionally substituted aromatic or heterocyclic radical.
