A convenient and general synthetic method for spiro[4.n]alk-2-ene-1,6- diones and spiro[5.n]alk-2-ene-1,7-diones, which involves the intramolecular acylation of an α-sulfinyl carbanion, is described.

A novel free radical initiated ring expansion of haloalkyl β-keto esters is described.Following alkylation of the β-keto ester with the appropriate dihalide, the resulting halide is treated at reflux with tri-n-butyltin hydride.Rearrangement to the homolo
