On the synthesis of aryl cyclopropanes from γ-benzenesulfonylalkyl tin derivatives and n-butyllithium

Article abstract of DOI:10.1016/S0040-4039(00)79033-2

γ-Benzenesulfonyloxyalkyl tin derivatives readily available from γ-hydroxyalkyl selenides, n-butyllithium and trialkyl tin chlorides react with n-butyllithium and stereospecifically lead to aryl cyclopropanes. The transformation is quite general and allows the synthesis of α,β-di- and trisubstituted ones.
