标题:Process for synthesis of syn azido epdxide and its use as intermediate for the synthesis of amprenavir and saquinavir

摘要:A novel synthetic route to the syn-azido epoxide of formula 5 includes cobalt-catalyzed hydrolytic kinetic resolution of a racemic mixture of the azido-epoxide. Reaction steps include subjecting an allylic alcohol to epoxidation with mCPBA to obtain a racemic epoxy alcohol; ring opening the epoxy alcohol with azide anion to obtain an anti-azido alcohol, which can then be selectively tosylated at the primary alcohol; treating the tosylate with base to obtain the racemic azido-epoxide; and subjecting the racemic azido-epoxide to cobalt-catalyzed hydrolytic kinetic resolution to obtain the syn-azido epoxide of formula 5. The compound of formula 5 may be used as a common intermediate for the asymmetric synthesis of HIV protease inhibitors, such as Amprenavir, Fosamprenavir, Saquinavir, and formal synthesis of Darunavir and Palinavir.

摘要:The present invention relates to a method for the synthesis of enantiomerically and diastereomerically enriched 4-alkoxy-, 4-hydroxy- or 4-aryloxy- substituted tetrahydro-furo[3,4-b]furan-2(3H)-ones by aldol coupling of a suitable hydroxyl-protected hydroxy-acetaldehyde and 4-oxobutanoic acid or an ester thereof, and subsequent removal of the protecting group from the aldol compound and (optionally simultaneous) cyclizations and acetal formation under acidic conditions in the presence of an alcohol, followed by optional isolation of the desired compounds. The invention also relates to compounds according to formulae [Xl] and [XII].

摘要:A family of triazole derivatives is described. Also described is the use of these triazole derivatives in treating or preventing viral infections, such as human immunodeficiency virus (HIV) infections, and the diseases caused by these infections, such as acquired immunodeficiency syndrome (AIDS). The triazole derivatives, for example, comprise a central triazole group with two substituents comprising an aryl or heteroaryl group. Exemplary derivatives showed excellent HIV inhibitory activity against both wild-type and selected mutant strains of HIV.
