Selective Syntheses of Δ(α,β) and Δ(β,γ) Butenolides from Allylic Cyclopropenecarboxylates via Tandem Ring Expansion/[3,3]-Sigmatropic Rearrangements
[Image: see text] Allylic cyclopropenecarboxylates undergo ring expansion reactions to give 2-allyloxyfuran intermediates, which subsequently rearrange to Δ(β,γ) butenolides via Claisen rearrangement or to the corresponding Δ(α,β) butenolides via further Cope rearrangement. Also described are method...
