Abstract

Reactions of epoxides with strong, non-nucleophilic bases have been widely used for the synthesis of allylic alcohols. 1 Bases used to effect these rearrangements include R2NLi, 1a, b R2NMgBr, 1a, c diethylaluminum 2, 2, 6, 6-tetramethylpiperidide (DATMP), 1a, d and i- Pr2NLi/KO-t-Bu (LIDAKOR). 1e We report here that a silyl substituent can affect the regiochemical course of these rearrangements.
