A new synthesis of several 6-alkyl, 6-aryl, or 6-heteroaryl 2-(3H)-benzofuran-3-ones, by action of thionyl chloride on the easily accessible (4-substituted 2-oxo-3-cyclohexen-1-yl)acetic acids is described.The action of thionyl chloride on some simple der

2(4H)-5,6-Dihydrobenzofuranones 3 gave, when treated with pyridine hydrochloride at 200 deg, the corresponding arylacetic acids 1 in good yields, whereas the aza analogues, the tetrahydrooxindoles 6 gave indoles in poor yields.The oxidation products of 3 (11 and 13) and of 6 (12, 14 and 15) gave, with the same reagent, benzofuranones and oxindoles, respectively, both in good yields.
