(Chemical Equation Presented) A catalytic enantioselective approach to the eudesmane sesquiterpenoids is reported. The strategic use of a palladium-catalyzed enantioselective alkylation of vinylogous ester substrates forged the C(10) all-carbon quaternary

A remarkable effect of (C6F5O)3Al for promoting the rearrangement of epoxy acylates via stable cation intermediates was found, and new methods for constructing chiral benzylic, vinylic, and acetylenic quaternary carbon centers were developed. During the study, the importance of the ionic nature of the O - metal bond in the intermediates of such epoxides was addressed. This method was applied to the asymmetric total synthesis of (S)-(+)-sporochnol A.
Competitive Intramolecular Cycloaddition and Tandem Cycloaddition/-Sigmatropic Rearrangement Sequence of Allenyl 3-Vinyl-2-cyclohexenyl Ethers: Evidence for Switching of the Reaction Pathway by the Substituent Effects

The base-catalyzed intramolecular cycloaddition reactions (t-BuOK, t-BuOH, 83 deg C) of variously substituted propargyl 3-vinyl-2-cyclohexenyl ethers have been investigated.The reaction proceeded smoothly via the initial isomerization to the corresponding
