文摘N-glycinylmaleamic acid(GMA) was synthesized by using maleic anhydride and glycine.Five synthesis methods for N-glycinylmaleimide(GMI)were compared.Among them the method using triethylamine to dehydrate was found to be the best.Their structures were confirmed by fourier transform infrared spectroscopy(FTIR) and nuclear magnetic resonance spectrum(HNMR).
