Anwendungen & Verwendung
Verwenden
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.
