An iodine-catalyzed regioselective sulfenylation of imidazo[1,5-a]quinolines was developed under metal- and oxidant-free reaction conditions. Using disulfides or thiophenols as sulfenylating agents, 3-sulfenylimidazo[1,5-a]quinoline derivatives were obtained in good to excellent yields with broad functional group tolerance. A multi-component reaction to generate 1-sulfenylated imidazo[1,5-a]pyridines
在无金属和无氧化剂的条件下,开发了碘催化的咪唑并[1,5- a ]喹啉的区域选择性亚磺酰基。使用二硫化物或硫酚作为亚磺酰化剂,可以良好的收率获得优异的3-亚磺酰基咪唑并[1,5- a ]喹啉衍生物,并且具有宽泛的官能团耐受性。还描述了产生1-亚磺酰化的咪唑并[1,5- a ]吡啶的多组分反应。初步生物学评估表明,某些3-亚磺酰化的咪唑并[1,5- a ]喹啉具有显着的抗癌活性。
