Procedimiento para la preparación de (1S,2R)-3-[[(4-aminofenil)sulfonil](isobutil)amino]-1-bencil-2-hidroxipopilcarbamato de (3R,3aS,6aR)-hexahidrofuro[2,3-b]furan-3-ilo

摘要

The present invention relates to a process for the preparation of (3R,3aS,6aR)-hexahydrofuro[2,3-b]furan-3-yl(1S,2R)-3-[[(4-aminophenyl)sulfonyl](isobutyl)amino]-1-benzyl-2-hydroxypropylcarbamate as well as novel intermediates for use in said process. (3R,3aS,6aR)-hexahydrofuro[2,3-b]furan-3-yl(1S,2R)-3-[[(4-aminophenyl)sulfonyl](isobutyl)amino]-1-benzyl-2-hydroxypropylcarbamate is particularly useful as an HIV protease inhibitor.
