| Abstract: | Analysis of the spectral data (1H NMR and13C NMR) indicates that out of ten N-hydroxypiperidin-4-one oximes 3a-j, the compounds 3b and 3c exist predominantly in chair conformation with the aryl and alkyl substituents in the equatorial positions, whereas the compounds 3d-j exist in boat conformation. The introduction of an oxime group at C-4 causes a flattening of the ring about C(5)-C(6) bond. The NOESY spectrum (Nuclear Overhauser effect) recorded for the compound 3d further supports the assigned boat conformation. |
