Convenient method for the synthesis of N-(ethyloxycarbonyl) ester derivatives from amino acids

Kanth,Periasamy

, p. 1523 - 1530 (2007/10/02)

Amino acids upon treatment with ethyl chloroformate in methanol in the presence of potassium carbonate give the corresponding N-(ethyloxycarbonyl) amino acid ester derivatives in good yields. These derivatives can be also synthesized by performing the reaction in THF in the presence of alcohols.
