摘要

Abstract A new reaction sequence for the synthesis of the sesquiterpene arenes (±)- wiedendiol B ((±)-1) and the siphonodictyal B derivative (±)-21 consists in the coupling of (±)- drimanoyl chloride ((±)-3) with lithiated and appropriately substituted aromatic synthons to furnish the ketones (±)-7 and (±)-17 which were reduced to the benzyl alcohols (±)-8a, b and (±)-18a, b, respectively (Schemes 5, 4, and 12). The 9, 11-double bond of the drimenes (±) ...
