By stepwise and regioselective installation of functional groups, we have synthesized and characterized two pyridines, 3-fluoro-5-iodo-2-(methylthio)-6-(trimethylsilyl)isonicotinonitrile and 3-fluoro-5-iodo-2-methoxy-6-(trimethylsilyl)isonicotinonitrile, substituted with five different elements, not including hydrogen, using known and newly developed methods. Novel methodology for dehalocyanation of iodopyridines and rapid, high-yielding microwave-assisted acidic hydrolysis of 2-fluoropyridines to their corresponding 2-pyridones are disclosed.
通过逐步和区域选择性地安装官能团,我们利用已知和新开发的方法合成了两种吡啶,3-氟-5-碘-2-(甲硫基)-6-(三甲基硅基)异烟腈和 3-氟-5-碘-2-甲氧基-6-(三甲基硅基)异烟腈,这两种吡啶被五种不同的元素(不包括氢)取代。公开了碘吡啶脱卤氰化的新方法,以及 2-氟吡啶快速、高产的微波辅助酸性水解为相应的 2-吡啶酮的方法。
