Remarkable Selectivity in Addition of Alcohols to Epoxydienes of 5,7 Bicyclic and 5,7,6 Tricyclic Systems
摘要:
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 S(N)2' process affording 1,6- and 1,4-dioxygenated derivatives, respectively.
