Abstract
1,2,2,6,6-Pentamethyl-3,5-dimethylene-4-piperidone was synthesized, whereas analogous compounds in the 4-piperidone series could not be isolated. An unusual reaction of the compound obtained with primary aliphatic amines, consisting of successive addition of the amine at the C=C bonds, with a possible formation of an intermediate bicyclic adduct and further elimination of methylamine, was detected.
