1.3- Dimethylcyclopentane

A facile intramolecular carbomagnesiation becomes possible by inserting one more carbon between the reactive magnesium center and the double bond. For example, when a 6-chloro-l-heptene was refluxed with magnesium, 1,2-dimethylcyclopentane (cis/trans = ca 1/4) was obtained in 88% yield after hydrolysis (Scheme 47) °. The cyclization shows a 5-exo-trig selectivity and the product derived from 6-endo-trig cyclization (methylcyclohexane) is not observed. [Pg.654]
