Linton, Elizabeth C. published the artcileCatalytic Enantioselective Meerwein-Eschenmoser Claisen Rearrangement: Asymmetric Synthesis of Allyl Oxindoles, Recommanded Product: (R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole, the publication is Journal of the American Chemical Society (2008), 130(48), 16162-16163, database is CAplus and MEDLINE.

The first catalytic, enantioselective Meerwein-Eschenmoser Claisen rearrangement has been achieved. Palladium(II) BINAP or phosphinooxazoline catalysts were employed to generate oxindole products, e.g. I, with 100% conversion and up to 92% ee.
