    摘要: The present invention relates to an improved process for the preparation of atazanavir bisulfate, an inhibitor of retroviral aspartate protease. The process of the present invention comprises conversion of 1,1-dimethylethyl[(2S,3R)-4-chloro-3-hydroxy-phenylbutan-2-yl]carbamate (Formula II) into 1-[4-(pyridine-2-yl)-phenyl]-4(S)-5 hydroxy-2-N-tert-butoxycarbonylamino-5(S)—N—(N-methoxycarbonyl-(L)-tert-leucyl)amino-6-phenyl-2-azahexane (Formula VII) without isolating intermediate compounds formed therein, followed by its subsequent conversion to atazanavir or its bisulfate salt.

    摘要: The present invention relates to a process for enantioselective synthesis of substituted pyridinylmethyl sulfinyl-benzimidazole of compound of Formula (I). The process includes enantioselective catalytic oxidation of a substituted pyridinylmethyl prochiral sulfide derivative of compound of Formula (II) with an oxidizing agent in the presence of a chiral transition metal complex and a base in the absence of an organic solvent.
