Intramolecular Michael reaction of bis-α,β-unsaturated esters 1 forming 2 was carried out by the action of a trialkylsilyl trifluoromethanesulfonate in the presence of a tertiary amine; the product was transformed into ricciocarpin A 8.
Deconjugation of α,β-Unsaturated Esters and an Intramolecular Michael Reaction of Bis-α,β-unsaturated Esters with Trialkylsilyl Trifluoromethanesulfonate in the Presence of Tertiary Amine: Synthesis of (+/-)-Ricciocarpin A
