Thio- and Seleno-lactonizations of Alkynoic Acids

Regio- and stereo-specific thio- and seleno-lactonizations of hept-4-ynoic acid (1a), hex-4-ynoic acid (1b), and pent-4-ynoic acid (1c) can be achieved by treatment of benzenesulphenyl chloride and benzeneselenyl chloride using a hydrogen chloride capture

Selenolactonization of Alkynoic Acids with N-Phenylselenophthalimide: Novel Isomerization Reaction of a Vinyl Selenide

Selenolactonization is stereoselective and regiospecific for hex-4-ynoic and hept-4-ynoic acids (1a) and (1b), but pent-4-ynoic acid (1c) gives a mixture of stereoisomers.
