Application
- 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.
