Synthesis of the Core Structure of Salicylihalamide A by Intramolecular Suzuki Reaction
摘要:
An intramolecular Suzuki coupling was used to establish the core structure of the benzolactone enamide salicylihalamide A. This strategy combines a diastereoselective hydroboration with a subsequent cross-coupling.

Several aldol products resulting from Evans aldol reactions were converted to primary alcohols. After conversion to the corresponding tosylates, heating with Nal and DBU in dimethoxyethane (glyme) effected clean elimination to the terminal olefin. This simple one-pot procedure was applied to other tosylates and a tosylate derived from a homoallylic alcohol. The latter gave rise to a diene.
