Description

  • General description: L-tert-Leucine is an amino acid used as a precursor for synthesizing chiral tridentate Schiff base ligands.[1]
  • Application: L-tert-Leucine can be used:As a key precursor in the synthesis of a chiral phosphinooxazoline ligand, (S)-tert-butylPHOX.[2]In the synthesis of chiral copper(II) polymers that can catalyze the kinetic resolution of secondary alcohols by acylation.[3]In metal-free tandem radical cyclization reactions to synthesize 6-alkyl/acyl phenanthridines.[4]In the preparation of tert-leucine-derived N-acetylthiazolidinethione auxiliary that provides high levels of diastereoselection in acetate aldol reactions with a variety of aldehydes.[5]
