L-tert-leucine can be used as a catalyst for the enantioselective oxidative coupling and cyclization of hydroquinones to oxa[9]helicene. Used as a nutritional fortifier, animal feed additives, and used in the synthesis of pharmaceuticals. Amino acids are the basic components of protein, and one of its main physiological functions is as a raw material for protein synthesis.
