A general synthesis of 6-trichloromethylpterin, 2-chloro-3-trichloromethylquinoxaline and 2-amino-7-trichloromethyl-1,8-naphthyridine along with a series of trichloromethyl heterocycles (1–11) has been reported in one-pot mild neutral condition in good yield. This method is compared with the usual method using phosphorus pentachloride in phosphorus oxychloride.
在一锅中温和中性条件下,以良好的产率合成了6-三氯甲基蝶啶、2-氯-3-三氯甲基喹喉和2-氨基-7-三氯甲基-1,8-萘啶等一系列三氯甲基杂环化合物(1-11)。该方法与通常使用五氯化磷的磷酰氯方法进行了比较。
