Methoxycarbonyl-L-tert-leucine Usage And Synthesis

Description	Methoxycarbonyl-L-tert-leucine is a kind of amino acid deriviative. It is a very useful intermediate for efficient synthesis of the HIV protease inhibitor BMS-232632 as well as atazanavir bisulfate.

Chemical Properties	White Solid
Uses	The coupling of the two key intermediates, N-(methoxycarbonyl)-l-tert-leucine acylated benzyl hydrazine and chloromethyl ketone, via an S N 2 reaction furnished the amino ketone in high yield under our optimized conditions in practical synthesis of the HIV Protease Inhibitor Atazanavir via a Highly diastereoselective Reduction Approach.
