Preparation of Ring-Substituted (Arylsulfonyl)cyclopropanes and (Arylsulfonyl)bicyclobutanes from γ,δ-Epoxy Sulfones

Gaoni, Yehiel

, p. 2564 - 2571 (2007/10/02)

Treatment of γ,δ-epoxy sulfones 2 with n-butyllithium provides 1-(hydroxyalkyl)-2-(arylsulfonyl)cyclopropanes (3).Dehydration of the latter, when applicable, yields 1-alkenyl-2-(arylsulfonyl)cyclopropanes (5) which can be epoxidized and converted by a sec
