cis- and trans-2,6-Dimethylpiperidine have been purified by preparative VPC. The configurations of the bases have been confirmed by analysis of their PMR spectra, and of the spectra simplified by spin decoupling. One of the three isomeric 2,4,6-trimethylpiperidines has been purified by preparative VPC and shown by PMR spectroscopy to have the cis (2,4), cis (4,6), cis (2,6)-stereochemistry.
