(Chemical Equation Presented) Scoping out TIMO: A telescoped intramolecular Michael addition/proton transfer/ Horner-Wadsworth-Emmons olefination sequence was developed to provide rapid access to α-alkylidene-γ- butyrolactones (see scheme). The method was applied to prepare a range of tetrahydrobenzofuran-2,5-diones and related systems, and it was utilized in a short synthesis of enantiomerically pure (+)-paeonilactone B.
