설명

일반 설명

L-tert-Leucine is an amino acid used as a precursor for synthesizing chiral tridentate Schiff base ligands.

애플리케이션

L-tert-Leucine can be used:

• As a key precursor in the synthesis of a chiral phosphinooxazoline ligand, (S)-tert-butylPHOX.
• In the synthesis of chiral copper(II) polymers that can catalyze the kinetic resolution of secondary alcohols by acylation.
• In metal-free tandem radical cyclization reactions to synthesize 6-alkyl/acyl phenanthridines.
• 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.
