    Synthesis of 6-methoxy-N 2,N 2,N 4,N 4,N 5,N 5-hexamethylquinoline-2,4,5-triamine – a new representative of quinoline proton sponges
    摘要:
    [GRAPHICS]We report the synthesis of 4-chloro-2-methyl-5-nitro-and 2,4-dichloro-5-nitroquinolines, containing methoxy groups at positions 6 and 8. The reaction of these compounds with dimethylamine solution in alcohol was shown to produce not only aminodehalogenation products, but also resulted in nucleophilic substitution of the methoxy groups. The reduction of 6-methoxy-N-2,N-2,N-4,N-4-tetramethyl-5- nitroquinoline-2,4-diamine with subsequent methylation gave 6-methoxy-N-2,N-2,N-4,N-4,N-5,N-5-hexamethylquinoline-2,4,5-triamine, a new representative of quinoline proton sponges.

  • Molecular structure and protonation trends in 6-methoxy- and 8-methoxy-2,4,5-tris(dimethylamino)quinolines

    tendency of 7 to form anilinium cation is much higher if compared to 8. It has been also shown that basicity of 7 is the largest among all known derivatives of 4,5-bis(dimethylamino)quinoline and even slightly exceeds that of 1,8-bis(dimethylamino)naphthalene (parent proton sponge). This was attributed to the “buttressing effect” exhibited by the 6-MeO group. Stable double salts of 7 with picrate and perchlorate
    摘要 利用X射线测量、核磁共振谱和理论计算研究了2,4,5-三(二甲氨基)喹啉的6-甲氧基-7和8-甲氧基-8衍生物的分子结构和质子化趋势。已经发现,虽然固态中的 8 形成喹啉鎓类型的质子盐,但其异构体 7 表现为典型的质子海绵,使苯胺阳离子与被 peri-NMe2 基团螯合的质子。在溶液中,两种化合物同时在两个可能的中心单质子化,但如果与 8 相比,7 形成苯胺阳离子的趋势要高得多。 还表明,7 的碱度是所有已知的 4,5 衍生物中最大的-双(二甲氨基)喹啉,甚至略超过 1,8-双(二​​甲氨基)萘(母质子海绵)。这归因于 6-MeO 组表现出的“支撑效应”。获得并彻底研究了 7 与苦味酸和高氯酸阴离子的稳定复盐,这对于具有共轭氮杂和 NMe2 基团的吖嗪是前所未有的。

    Demethylation of methoxy groups in 6(8)-methoxy-2,4,5-tris(dimethylamino)quinolines with 48% HBr leads to nucleophilic substitution of the 4-NMe2 group with the formation of quinolones existing in solution and the solid state in the hydroxy form stabilized by intramolecular hydrogen bonding. Unlike HBr, the use of BBr3 in the case of the 8-methoxy derivative leads to the formation of 8-hydroxy-2,4
