## Abstract PMR characteristics of some isomeric 1βsubstitutedβ2,5βdimethylβ4βpiperidones are reported and major isomers shown to have a __trans__ 2,5βdimethyl configuration. Differences between benzylic methylene signals of isomeric 1βbenzyl analogs provide evidence of the preferred conformation o
