Dependence of the Lewis Acid-induced Reaction of β-stannyl Ketones upon Substitution Pattern. 1,2-Alkyl Migration versus Cyclopropanation

Article abstract of DOI:10.1246/cl.1992.1775

3-Stannylcyclohexanones fully substituted at 2 and 3 positions undergo a 1,2-alkyl migration and cyclopropanation.The balance of the reaction pattern depends upon the steric environment and migratory aptitude of the alkyl groups.
