A process for producing N-substituted amino compounds, a process for oxidizing an N-substituted amino compound with a microbe, or cell fragment or cell free extract thereof, and a process for oxidizing an N-substituted amino compound with a microbe, or cell fragment or cell free extract thereof and reducing the oxidized N-substituted amino compound to N-substituted-polyhydroxy piperidines based on N-substituted mannosamines, allosamines and altrosamines, N-substituted polyhydroxy pyrrolidines, and N-substituted polyhydroxy azetidines. In addition, a one pot process for producing N-substituted-polyhydroxy piperidines based on N-substituted mannosamines, allosamines and altrosamines, N-substituted polyhydroxy pyrrolidines, and N-substituted polyhydroxy azetidines from the respective sugar is disclosed. A second embodiment comprises novel compositions of N-substituted-amino-6-deoxy-2-ketohexuloses based on mannose, allose and altrose, N-substituted-amino-5-deoxy-2-ketopentuloses and 4-(N-substituted)-amino-1,3-dihydroxy-2-butanones.
