SYNTHETICALLY USEFUL TRANSFORMATIONS OF δ-SULTONES AND THIANE-1,1-DIOXIDES OBTAINED BY C-H INSERTION

摘要

S-Sultones and thiane-1,1-dioxides that carry a carbethoxy group at α-position, easily accessible by C-H insertion, are potentially useful synthetic intermediates. Their stereoselective alkylation, rearrangement and conversion to γ-lactones have been demonstrated.
