3- allyl phenylpropiolates intramolecular reactions

Intramolecular reactions of 3-(2- and 3-thienyl)allyl phenylpropiolates 311 and 312 gave lactones 313 and 314. Formation of 313 involves substitution into the 3-position of the thiophene, while formation of 314 involves substitution into its 2-position (65JHC225).
