Abstract

Abstract Solid-liquid phase transfer catalysis in the absence of any solvent efficiently promotes Michael additions of nitro alkanes and of diethyl N-acetylaminomalonate to phenyl vinyl sulfone and to phenyl vinyl sulfoxide. The adduct of the Michael addition to diethyl N- acetylaminomalonate to phenyl vinyl sulfoxide was converted by distillation under partial vacuum to diethyl N-acetylamino vinyl malonate which gave (±)-vinylglycine by ...
