A series of 1,2,3-triazole annulated chromen and quinolone derivatives have been synthesized by means of direct sp2 C–H functionalization in the presence of iso-propanol and potassium tert-butoxide. The reaction proceeds through homolytic aromatic substitution (HAS). This efficient as well as simple C–H functionalization methodology offers a straightforward route to 1,2,3-triazole annulated oxygen
在异丙醇和叔丁醇钾存在下,通过直接sp 2 C–H官能化合成了一系列1,2,3-三唑环氧化铬和喹诺酮衍生物。反应通过均相芳族取代(HAS)进行。这种高效且简单的C–H功能化方法为1,2,3-三唑环氧化的氧和氮杂环化合物提供了直接的途径。
