, p. 1077 - 1080 (2007/10/03)

(Chemical Equation Presented) Acid-catalyzed addition of alcohols to tricyclic dienyl epoxides such as 4 or bicyclic vinyl oxiranes such as 17 exclusively occurred at the vinyl terminus of unsaturated system through a typical SN2′ process affording 1,6- and 1,4-dioxygenated derivatives, respectively.
