L - leucine is a nonprotein source of chiral amino acids, due to the hydrophobic tert-butyl side chain has a bigger space steric hindrance, can be used for asymmetric synthesis of chiral inducer and asymmetrical separation of split reagent, in the synthesis of compound, it can effectively control the molecular conformation. As an important kind of pharmaceutical intermediates, L - uncle leucine is widely used in synthesis of inhibitors, biological active peptide, anticancer and antiviral drugs, such as drugs, such as HIV, wei (Atazanavir), drug hepatitis c virus (HCV) pop rui wei (Boceprevir), to pull a horse wei (Telaprevir), Narlaprevir and Vaniprevir. Therefore, is expected to the pharmaceutical industry, the demand for L - uncle leucine will present the trend of rising year by year. Along with our country social economy development and environmental protection consciousness enhancement, medicine and chemical industry need to not only improve the production capacity of L - uncle leucine, and need to create a green production process. My company using enzymatic production of L - uncle leucine, process
