Treatment of the diazomalonates (9a-d) of 2-phenylthio-3-butenol derivatives with catalytic rhodium acetate resulted in the sigmatropic rearrangement of six-membered allylsulfonium ylides to provide γ,δ-unsaturated seven-membered lactones (10a-d) in
New Entry to γ,δ-Unsaturated Seven-membered Lactones

The sigmatropic rearrangement of cyclic allyl-sulfonium ylides, generated from the diazo malonates of 2-phenylthio-3-butenol derivatives with catalytic rhodium acetate, afforded γ,δ-unsaturated seven-membered lactones in moderate to good yields.
