描述了两种有效的碘介导的经济方法,一种是经济的,而且是一锅法,可用于获得双(咪唑并[1,2 - a ]吡啶-3-基)硫烷和双(咪唑并[1,2 - a ]吡啶-3)。通过使用廉价的硫化钠作为硫源,直接将咪唑-杂环进行氧化均质偶合,在氯仿和乙酸中分别制得[-yl)二硫。这些策略是可扩展的,并且一系列底物以优异的产率提供了其相应的稳定的硫桥联咪唑-杂环。
The invention relates to compounds of formula (I): and their pharmaceutically acceptable salts and solvates, which are inhibitors of SSAO activity. The invention further relates to pharmaceutical compositions comprising these compounds and to the use of these compounds for the treatment or prevention of medical conditions wherein inhibition of SSAO activity is beneficial, such as inflammatory diseases and immune disorders.
