Enantiospecific total synthesis of (+)-pinguisenol 1, a sesquiterpene containing a cis-1,2,6,7-tetramethylbicyclo[4.3.0]nonane carbon framework incorporating two vicinalquaternarycarbonatoms and four cis-oriented methyl groups on four contiguous carbonatoms, isolated from a liverwort, is described. The orthoester Claisen rearrangement of the allyl alcohol 9, obtained from (R)-carvone, generates

The totalsynthesis of (±)-β-pinguisene 1 has been achieved by a propargylsilane-terminated cyclization of enone 2 as the key step. Compound 3 was transformed in a straight forward way in 10 steps to give β-pinguisene 1.

such as hydroazulene 2, bicyclooctane 4, or hydrindanone 12 can be easily obtained by Amberlyst 15 (A 15) catalyzed cyclizations of allyl- and propargylsilanes. The total syntheses of (±)-β-pinguisene 5 and (±)-pinguisenol 6 have been achieved by propargylsilane-terminated cyclizations of enone 11 as the key step. Compound 12 was transformed in a straight forward way to provide β-pinguisene 5 and pinguisenol

The first enantiospecific total synthesis of the sesquiterpene (+)-pinguisenol, the optical antipode of the natural product, and the analogues (−)-pinguisen-10-one and (+)-pinguisen-8,10-dione, starting from R-carvone are described.
