F. Donofrio et al., CONJUGATE ADDITION-ELIMINATION REACTIONS AS A NOVEL SYNTHETIC ROUTE TO DIALKYLATED ALPHA,BETA-UNSATURATED DIESTERS, Synlett, (1), 1996, pp. 63
The paper describes a novel synthetic route for mono- and dialkylation
of dimethyl 2-phenylseleno fumarate 1. The conjugate additions to 1 p
roceed regio- and stereoselectively. The subsequent oxidative eliminat
ions of phenylseleno group provide a convenient procedure for the synt
hesis of the title compounds.
