Tricyclodecadienone epoxides 5 do not form an enolate on treatment with lithium diisopropyl amide, but instead undergo an unusual stereoselective β-hydride transfer leading to alcohols 6.The same type of epoxy endo-alcohol was obtained from parent epoxy ketone 5 on reaction with metal hydrides and organolithium reagents.These alcohols readily undergo an intramolecular epoxide migration by a Payne-type rearrangement, to give endo-epoxides 9.
