Indirect Hidroquinone Succinoylation via a Photo-Fries Rearrangement. Application to the Synthesis of Enol Lactones

A photo-Fries rearrangement of hydroquinone succinates is the key step that allows the preparation of some γ-aryl enol lactones by dehydration of the corresponding aroyl propinoic acids.

Photochemical Versus Aluminium Chloride-Catalyzed Fries Rearrangement of Aryl Hydrogen Succinates. Synthesis of 2(3H)-Furanones

The photochemical and aluminium chloride-catalyzed Fries rearrangement of a series of aryl hydrogen succinates 3 a-f to the corresponding 4-oxoacids 1 a-f are compared.Both approaches are complementary: the photochemical process is more general and becomes the method of choice for the succinoylation of phenols supporting alkoxy or hydroxy substituents, while the classical rearrangement is superior in the presence of alkyl or halogen substituents.These results are applied to the preparation of the 2(3H)-furanones 2 a-f. - Keywords: Fries rearrangement; Photo-Fries rearrangement; Aryl hydrogen succinates; 4-Oxoacids; 2(3H)-Furanones.
