Abstract:
A facile and chemoselective one-pot synthesis of stable phosphorus ylides containing a β-amino group has been developed via reaction of triphenylphosphine, dialkyl acetylenedicarboxylate and 1,2-phenylenediamine in the presence of phenol or 2-aminophenol on its own at ambient temperature.
