    • The preparation of 5-sulfonamido-8-hydroxy-1,6-naphthyridine-7-carboxamides is disclosed. A 5-halo-8-hydroxy-1,6-napthyridine-7-carboxylic acid or acid ester in which the hydroxy is derivatized with a protecting group is reacted with a sulfonamide (e.g., an alkanesulfonamide, N-alkyl alkanesulfonamide, or alkanesultam) in the presence of a copper promoter and a chelating agent, followed by deprotection of the hydroxy group, and then coupling with an amine to obtain the 5-sulfonamido-8-hydroxy-1,6-naphthyridine-7-carboxamide. Alternatively, the hydroxy-protected 5-halo-8-hydroxy-1,6-napthyridine-7-carboxylic acid (or ester) is first coupled with an amine, the resulting carboxamide reacted with a sulfonamide followed by deprotection of the hydroxy group to obtain the 5-sulfonamido-8-hydroxy-1,6-naphthyridine-7-carboxamide. The 5-sulfonamido-8-hydroxy-1,6-naphthyridine-7-carboxamides are inhibitors of HIV integrase and are useful for treating HIV infection, preventing HIV infection, delaying the onset of AIDS, and treating AIDS.
    • 公开了5-亚磺酰氨基-8-羟基-1,6-萘啶-7-甲酰胺的制备。 将其中羟基用保护基团衍生化的5-卤代-8-羟基-1,6-萘并噻唑-7-羧酸或酸酯与磺酰胺(例如烷基磺酰胺,N-烷基烷烃磺酰胺或烷烃磺酰胺)反应 )在铜促进剂和螯合剂的存在下反应,然后脱保护羟基,然后与胺偶联,得到5-亚磺酰氨基-8-羟基-1,6-萘啶-7-甲酰胺。 或者,首先将羟基保护的5-卤代-8-羟基-1,6-萘并吡喃-7-羧酸(或酯)与胺偶联,得到的羧酰胺与磺酰胺反应,然后将羟基脱保护 得到5-亚磺酰氨基-8-羟基-1,6-萘啶-7-甲酰胺。 5-亚磺酰氨基-8-羟基-1,6-萘啶-7-甲酰胺是HIV整合酶的抑制剂,可用于治疗HIV感染,预防艾滋病毒感染,延缓艾滋病的发病和治疗艾滋病。
