Abstract
An amino protection method was developed in which phthalic anhydride was used as the amino protection group, N,N-dimethylformamide (DMF) as solvent, L-threonine and L-serine with hydroxyl groups in side chain as the protected amino acids.The structures of products were confirmed by IR、1H NMR and 13C NMR. It is an efficient and simple protection method of amino acids with a hydroxyl group in the side chain.In addition, the synthetic method avoids the side reaction and significantly improves reaction yields(over 90%).
