10. 8-Octenyl radicals prefer to cyclize in an 8-endo rather than 7-exo fashion where possible (B. Giese, B. Kopping, T. Göbel, J. Dickhaut, G. Thoma, K. J. Kulicke, F. Trach, Organic Reactions, 1996, 48, 301 and references therein). For examples of 7-exo-trig radical cyclization, see: D. L. Boger, R. J. Mathvink, J. Org. Chem., 1988, 53, 3377 and ref 6(b).
