Application
L-Tyrosine Ethyl Ester Hydrochloride is used as a medical and organic intermediate and as an important amino protective agent. It is also used to introduce t-Boc protect gene.
Papain is also used for synthesizing poly(L-tyrosine) and poly(L-glutamic acid) using L-tyrosine ethyl ester hydrochloride and L-glutamic acid diethyl ester hydrochloride as the substrates, respectively. The protease-catalyzed copolymerization of amino acids is first achieved by papain using L-glutamic acid ester and various amino acid esters as substrates.
A mixture of L-tyrosine ethyl ester hydrochloride, the appropriate acid anhydri-des, triethylamine and dry tetrahydrofuran, was warmed for an hour in an atmosphere of nitrogen. After removing the amine salt, Ic and Id became crystalline on standing overnight in the cold.
