In an undivided cell, using N-phenylglycine ethyl ester as the model substrate, the reaction conditions were optimized. The results showed that the optimal reaction condition was reacting under 6 mA constant current for 3 h by utilizing nickel and graphite plate as anode and cathode materials respectively, 2.0 equiv. NaBr as the electrolyte, EG/DMA(3:1) as the mixed solvent at room temperature and air condition. The transesterification reaction could afford various corresponding glycine derivatives up to 88% yield. This mild reaction condition without adding any transition metal, acid or base, was complied with the concept of green chemistry. In addition, gram scale experiment synthesized 1.32 g of esterification products successfully, which also demonstrated the potential value of electrochemical transesterification of glycine derivatives.

Key words: electrochemistry, glycine derivatives, transesterification
