Abstract:

Inhibitors of HIV-1 protease were developed to act specifically on this enzyme class, with high affinity and high complementarity to the catalytic site of the protein, intrinsically competing with the natural substrates. The (2S,3S)-N-Boc-3-amino-1,2-epoxy- 4-phenylbutane (1) and its diastereomer of configuration (2R,3S) (2) are key intermediates in the preparation of some important antiretroviral compounds such as saquinavir, amprenavir, atazanavir and lopinavir. Thus, in this work we have investigated a new method for the stereoselective preparation of these chiral intermediates using organomagnesium reagents complexed with lithium chloride.
