sesquiterpenes isocomene 1 and β-isocomene 22 have been synthesized starting from 1,7-octadien-3-one 10 in a stereoselective manner. In the key step 12 → 13 (Scheme 5) the C-7, C-8-bond was formed by an intramolecular thermal enereaction. Further transformations of 13 (Scheme 6) involved successively ring contraction 18 → 19, elimination 21 → 22 and olefin isomerization 22 → 1.

For many reactions next to a carbonyl group, the use of O-silylated enolatechemistry offers improvements in yield and selectivity over the corresponding reactions of Group I metal enolates. In the case of α-alkylation of carbonylcompounds, Lewis-acid (TiCL4 or ZnBr2) promoted phenylthioalkylation of O-silylated enolates 3 by α-chlorosulphides 4 (R3=H, Me, Prn, Pri, But, and Me3Si), followed by reductive
Less highly substituted silyl enol ethers are regiospecifically prepared in high yield, around room temperature under kinetic conditions, from unsymmetrical cyclic ketones and magnesium bis(diisopropylamide) [(DA)2Mg] in THF/heptane. This high regioselectivity is markedly higher than these reported for bromomagnesium diisopropylamide (DAMgBr); it is also similar to this of LDA/DME at −78°C, but (DA)2Mg

We describe an efficient totalsynthesis of the sesquiterpenes (±)-β-isocomene and (±)-isocomene using a Lewis acid-promoted [3 + 2] cycloaddition of allyl-tert-butyldiphenylsilane as the key-step.
