Использование
L-tert-Leucine is an essential amino acid and makes up one third of our muscle protein. It can be used as a food additive. It is used in the formation of sterols. It is used in the production of cobalt oxazoline palladacycles complex, which acts as a catalyst in the rearrangement of prochiral N-aryl trifluoroacetimidates to allylic amides yielded in significantly higher enantioselectivities with the (S)-(pR)-diasteroisomer.

Общее описание
L-tert-Leucine (L-Tle) is an essential non-natural amino acid often used as a template to induce asymmetric synthesis, and the product has high stereoselectivity. It is a non-polar amino acid, and its tert-butyl group has significant hydrophobicity and steric hindrance, which can control molecular conformation in a chemical reaction and form a chiral compound. Hence, L-tert-leucine is commonly used as an inducer or a template in asymmetric synthesis. As a vital chiral intermediate, L-tert-leucine is widely used to synthesise anti-cancer, anti-viral, and biological inhibitors. In addition, L-tert-leucine is an essential additive in the food and cosmetic industry[1].
