CONVERSION OF LACTONE INTO LACTONE HEMITHIOACETAL AND SYNTHESIS OF ENOL LACTONE
Chemistry Letters, 1981Abstract Lactone hemithioacetal was synthesized in good yield from ω-phenylthiocarboxylic acid derived from lactone, and it was converted into enol lactone via the corresponding sulfoxide.

C R C Critical Reviews in Food Science and Nutrition, 1976
Lactones represent another important class of flavor compounds that have been found in a wide variety of foods although traditionally they have been mainly associated with dairy products. This review summarizes their occurrences in foods along with their formation pathways, sensory properties, and isolation, identification, and synthesis techniques ...

American Journal of Contact Dermatitis, 1996
Sesquiterpene lactones are a large, diverse group of chemicals found in several plant families that cause allergic contact dermatitis. The biological, botanical, allergenic, and structural significance of sesquiterpene lactones is explored as well as the clinical characteristics of cutaneous reactions.

Preparation of lactones via tricarbonyliron–lactone complexes
J. Chem. Soc., Perkin Trans. 1, 1981A number of tricarbonyliron–lactone complexes have been prepared from vinyl oxirans by treatment with pentacarbonyliron. In certain cases two η3-allyl complexes were isolated from a single vinyl oxiran. Oxidation of the complexes by cerium(IV) ammonium nitrate in acetonitrile leads predominantly to β-lactones.
