The present invention relates to a carbonic acid ester compound of the following formula (1):
1
in which X, Y, and Ar are defined in the specification, which can be easily combined with the amino group of an amino acid or removed therefrom under mild conditions, whereby the amino group can be effectively protected during peptide syntheses, process for preparing the same, and use of the same. Since the amino acid derivatives thus protected have high thermal and chemical stabilities and good solubility for organic solvents, peptides can be synthesized at a low cost with a high yield.
本发明涉及以下式(1)的
碳酸酯化合物:
其中X、Y和Ar在说明书中有定义,可以在温和条件下与
氨基酸的
氨基团轻松结合或从中移除,从而在肽合成过程中有效保护
