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.
