Study on Synthesis of N-hydroxyphthalimide Ester(NHP Ester)
A synthesis method of N-hydroxyphthalimide(NHP ester)is reported.Using commercially available amino acids as raw materials.Firstly,the amino group on the amino acid is modified,and the products are esterified with N-hydroxyphthalimide.NHP esters with different substituents can be obtained by this method.This method is simple safe,operation and efficient.
