A New Synthesis of Alkyl (E)-(3-Dimethylamino)acrylates. -The stereoselective synthesis of title compounds (III) and (VI) is achieved by reaction of Vilsmeier reagent, in situ generated from DMF and SOCl2, with ketene acetals. Similar yield is achieved when the reagent is introduced directly. -(ROBERTSON, J. M.; JONES, I. W.; KAYNE, K. M.; CONTRERAS, C. G.; WITTER, D. J.; BATES*, R. B.; HALL, H. K.
