  • Patent number: 6362346
    Abstract: This invention pertains to a process for making &agr;-methylene-&ggr;-butyrolactone by acid-catalyzed rearrangement of tetrahydro-3-furoic acid. In a further embodiment, when tetrahydro-3-furoic acid is treated with acetic anhydride and an acid catalyst, &agr;-acetoxymethyl-&ggr;-butyrolactone is produced in high yield. Under basic conditions, &agr;-acetoxymethyl-&ggr;-butyrolactone can readily form&agr;-methylene-&ggr;-butyrolactone by the elimination of acetic acid. These reactions provide &agr;-methylene-&ggr;-butyrolactone by novel routes which do not require butyrolactone or formaldehyde.
