6-heptadiene (14) has been studied experimentally. A series of ab initio molecular-orbital calculations on the course of the reaction were carried out and the results were compared to those for the corresponding intramolecularcarbolithiation of an isolated double bond. The Li-C interactions found in the transition state by this theoreticalstudy support a carbolithiation pathway for the cyclization of
