used for the synthesis of the sesquiterpenes (+)-albicanol, (+)-drimanol, and (+)-drimanic acid. Starting from all-trans-farnesol, (+)-albicanol could be prepared in seven steps in an overall yield of 14.9 %. Furthermore, a highly diastereoselective hydrogenation of (+)-albicanol to give (+)-drimanol has been developed. We used the synthesized (+)-drimanic acid to achieve the first synthesis of the marine
A New Approach to Sesquiterpene Arenes of the 9,11-Drimenyl Type (= [(1E,2RS,4aRS,8aRS)-Octahydro-2,5,5,8a-tetramethylnaphthalen-1(2H)-ylidene] methyl Type)

A new reaction sequence for the synthesis of the sesquiterpenearenes (±)-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)
