Abstract Pyridine derivatives (4a, d, e) were reacted with carbon disulfide in dry tetrahydrofurane (THF) in the presence of potassium tert-butoxide under Argon to yield thiopyanopyridine derivatives (7, 10). Also (2a, 4c) were reacted with carbon disulfide under the same condition producing the dithioacetal derivatives (13) which were converted to hipyridyl derivatives (14) via reaction with cyanothioacetamide
摘要 吡啶衍生物 (4a, d, e) 在无水四氢呋喃 (THF) 中,在叔丁醇钾存在下,在氩气下与二硫化碳反应,生成噻吩并吡啶衍生物 (7, 10)。同样(2a,4c)在相同条件下与二硫化碳反应,产生二硫代缩醛衍生物(13),通过在异丙醇和异丙醇钠中与氰硫代乙酰胺反应将其转化为吡啶基衍生物(14)。
