One of the few counterexamples to the general preference for γ- over δ-lactone formation (except in cases of overriding electronic factors or ring strain) is that 4-hexenoic acid reportedly gives the δ-lactone upon treatment with iodine:

We use Heathcock's convention of threo/erythro nomenclature: Pirrung, M. C.; Heathcock, C.H. J. Org. Chem. 1980, 45, 1727. The starting threo acids 1j and 1k were prepared from their ethyl esters (no epimerization occurred during saponification), which in turn were available by the threo-selective methylation procedure reported by Frater and by Seebach: (a) Prater, G. Helv. Chim. Acta 1979, 62, 2825. (b) Seebach, D.; Wasmuth, D. Helv. Chim. Acta 1980, 63, 197. The corresponding erythro isomers were isolated from a mixture resulting from the condensation of lithio ethyl propionate with either acrolein or methacrolein.
