Toepassing

Ethyl L-pyroglutamate can be used as a pharmaceutical active molecule and organic synthesis intermediate, such as for the synthesis of biologically active molecule HIV integrase inhibitors. In synthetic conversion, the nitrogen atom in the amide group can be coupled with iodobenzene, or the hydrogen on the nitrogen atom can be converted to a chlorine atom. In addition, ester groups can be converted into amide products through aminoester exchange reactions.
