The Chemistry of Vicinal Tricarbonyls. A New Synthesis of Substituted Furans.

Enolates of acyl phosphoranylidene carboxylates react with aldehydes to form secondary alcohols which undergo intramolecular addition to the central carbonyl of a vicinal tricarbonyl unit, generated in a separate step.The resulting dihydrofuranols undergo acid-catalyzed dehydration to form 3-hydroxyfuran-2-carboxylates.
