| | L-tert-Leucine Usage And Synthesis |
| Description | L-tert-Leucine is an essential amino acid making up one third of our muscle protein. L-tert-leucine is important in developing chiral pharmaceutically active chemicals. It can be used as a food additive. It is used in the formation of sterols. It can also be used as the catalyst in the production of cobalt oxazoline palladacycles complex. It can also be used for the production of Chiral tridentate Schiff base ligands.

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. | | Synthesis Reference(s) | Organic Syntheses, Coll.
