L-tert leucine is a key side chain in the synthesis of the antiviral drug Azanavir, which is a protease inhibitor class of antiretroviral drugs that can be used to treat human immunodeficiency virus (HIV) infection. It can also be used for:
(1) As a key precursor for the synthesis of chiral pho sphine oxazoline ligand (S) - tert butylphosphate;
(2) In the synthesis of chiral Chemicalbook copper (II) polymers, kinetic separation of secondary alcohols can be achieved through acylation catalysis;
(3) Synthesize 6-alkyl/acylpyridine in a metal free tandem radical cyclization reaction;
(4) In the preparation of N-acetylthiazolidine-sulfone adjuvants derived from tert leucine, high levels of non enantioselectivity are provided in the reaction of ace taldehyde with various aldehydes.
