The Baylis–Hillman adducts of aryl aldehydes and alkyl acrylates are efficiently oxidized to the corresponding α-methylene-β-keto esters with the Dess–Martin periodinane. The attempted Swern oxidation of the same adducts resulted in SN2′-type substitution of the allylic hydroxyl group by chloride.
芳基醛和丙烯酸烷基酯的Baylis-Hillman加合物可被Dess-Martin高碘烷有效地氧化为相应的α-亚甲基-β-酮酸酯。相同加合物的尝试的Swern氧化导致烯丙基羟基被氯化物的S N 2'型取代。

Abstract Anhydrous FeCl3 and Yb(OTf)3 are utilised as new reagents for the stereoselective isomerisation of acetates of the Baylis–Hillmanadducts to both (Z) and (E) trisubstitutedalkenes respectively.
