The present invention relates to a process for the preparation of darunavir, a nonpeptide protease inhibitor (PI), useful for the treatment of HIV/AIDS patients harboring multidrug-resistant HIV-1 variants that do not respond to previously existing HAART regimens. The present invention further relates to processes for the stereo-directed preparation of darunavir intermediates, in particular (3R,3aS,6aR)-hexahydrofuro [2,3-b] furan-3-ol and to certain novel intermediates obtained by such processes. |
