英文摘要：

For the development of new chiral ligands,reducing the cost of chiral catalysts and examining the universality of condensation and reduction of aromatic aldehydes with chiral amino acid ester,we designed and synthesized a new 3,4-methylenedioxyphenyl aziridino carboxylic acid ester from L-serine through esterification,condensation and reductive amination,which developed a highly efficient and convenient method for synthesis this kind of optically active compounds.The structure of aziridino carboxylic acid ester was confirmed by IR,1H NMR,13C NMR and HRMS.
