| Abstract: | L-trytophan methyl/ethyl ester hydrochloride,L-histidine methyl ester hydrochloride and L-proline methyl/ethyl ester hydrochloride were synthesized by reacting with three kinds of heterocyclic amino acids in a methanol/alcohol in the presence of thionyl chloride,and high yield product was produced. The structures of these compounds were characterized by NMR spectroscopy,IR spectroscopy and elemental analysis. Three types of heterocuclic amino acid esters were prepared by amino acid ester hydrochiloride in s... |
