Synthesis of Enol Lactones of 3-Aroyl-2-(thienylmethylene)-propionic Acids and their Conversion into the Corresponding 4-Arylbenzothiophene-6-carboxylic Acids

Heterocyclic aldehydes such as 2-thiophenecarbaldehyde (1) condense with 3-aroylpropionic acids 2 or their sodium salts to give the enol lactones 3a-d of 3-aroyl-2-(2-thienylmethylene)propionic acids.Isomerization of 3a-d leads to the corresponding 4-aryl
