The invention relates to a three-step synthesis of vinyl glycine (1) using a cheap, commercially available starting material (3-butenenitrile (2)) and using cheap, simple reagents. Also disclosed is a convenient optical resolution of the N-tert.butyloxycarbonyl derivative by papain-catalyzed enantioselective esterification in a two-phase system.
