Bump the base : This study reports the discovery of the base‐induced Z ‐to‐ E isomerization of exo ‐glycals bearing an electron‐withdrawing group (EWG). The scope of this novel transformation regarding the carbohydrate unit is also discussed. After elucidating the mechanism, preparation of novel ( E )‐ exo ‐ glycals was performed (TBS= tert ‐butyldimethylsilyl).
