A Practical Route for the Preparation of Substituted 6-oxo-2-Hexenoate Derivatives.

-The reaction of 2-hydroxy-3-butenoates [cf. (I)] with the aldehydes (II) generates alkyl allyl ethers which undergo Claisen rearrangement to give 6-substituted 6-oxo-2-hexenoates (III). Acetaldehyde diethyl acetal (IV) and benzylideneacetone (VI) react similarly under these conditions. -(

The synthesis and characterization of poly(4-hydroxystyrene) (PHS) and poly(4-vinylphenol) (PVPh) by the polymer modification route are reported. Polystyrene prepared by free-radical and anionic polymerization was acetylated quantitatively to poly(4-acetylstyrene) (ACPS) with acetyl chloride and anh
