Dependence of the Lewis Acid-Induced Reaction of β-Stannyl Ketones upon Substitution Pattern: Cyclopropanation versus 1,2-Alkyl Migration

Article abstract of DOI:10.1246/bcsj.66.1258

3-Stannylcyclohexanones fully substituted at 2 and 3 positions underwent a 1,2-aklyl migration, along with the cyclopropanation.The balance of the reactions depended upon the steric environment and migratory aptitude of the alkyl groups.
