Abstract

The synthesis in our laboratories of a wide variety of nicotine analogues has served as the basis for a range of chemical investigations. We have examined the effect of substituents on nicotine’s structure, conformation, and chemical reactivity. The methylation of nicotine and a wide variety of nicotine analogues has been studied. Three modes of alkylation are observed: pyridine and pyrrolidine, the latter occurring either cis or trans to the pyridine ring. The results of these alkylations are evaluated in terms of the Curtin-Hammett principle and the Winstein-Holness equation. Attention is focused on the effect of conformation on chemical reactivity. Ground state and transition state reactivity modes of the Menschutkin reaction are presented.
