Conformation of the two stereoisomers, α and β, of 2, 3-dimethylpiperazine, obtained by the high-pressure, catalytic reaction of ethylenediamine and 2, 3-butanediol, was determined. Since the α-isomer was resolved into d- and l-optical isomers, this must have the trans (aa or ee) conformation, while irresoluble β-isomer must have the cis (ae or ea) conformation. This fact was proved by separate syntheses of cis-and trans-2, 3-dimethylpiperazine.
