The total synthesis of (+)-cyperolone, an eudesmane-derived sesquiterpenoid from Cyperus rotundus, is described. The de novo synthesis was accomplished via a 15 step sequence starting from (R)-(-)-carvone. The synthetic route features a platinum-catalyzed
Regioselective isomerisation of highly substituted 1- methylenecyclohexenepoxides to the corresponding allylic alcohols. Influence of the base and of the protecting groups

Highly substituted 1-methylenecyclohexenepoxides 3, useful building blocks for a projected synthesis of wailupemycin A (1), were synthesized from (R)-carvone in eight synthetic steps in 23-40% overall yield. The regioselectivity of the subsequent isomeris
Efficient addition of cerium(III) enolate of ethyl acetate to ketones: application to the synthesis of β-ethoxycarbonylmethyl α,β-unsaturated ketones

The cerium(III) enolate derived from ethyl acetate was shown to undergo facile addition with ketones.With conjugated enones, 1,2-addition products were formed exclusively.Oxidative 1,3-oxygen transportation of these products provides an efficient route to
