Visible light induced regioselective C5 halogenation of 8-aminoquinolines with 1,3-dihalo-5,5-dimethylhydantoin in continuous flow
摘要:
An efficient and convenient method for remote C5 halogenation of 8-aminoquinoline derivatives was developed in continuous flow at room temperature. This method employed inexpensive 1,3-dibromo-5,5-dimethylhydantoin (DBDMH) and 1,3-dichlro-5,5-dimethylhydantoin (DCDMH) as halogenation reagents and visible light to catalyze the reaction. The reaction is scalable to gram-scale and proceeded with air and moisture tolerance, good functional group compatibility, and outstanding site selectivity, providing a new pathway for C5 halogenation of 8-aminoquinolines.

The use of cobalt as catalyst in direct CH activation protocols as a replacement for more expensive second row transition metals is currently attracting significant attention. Herein we disclose a facile cobalt-catalyzed CH functionalization route towards sultammotifsthroughannulation of easily prepared arylsulfonamides and alkynesusing8-aminoquinoline as a directinggroup. The reaction shows

for the first time as an efficient and versatile oxidant in the catalytic C–H activation reaction. By using sodium chlorate as the oxidant, a highly regioselective cobalt-catalyzed oxidativeannulation of aryl sulfonamides with alkynes has been developed and can be extended to the annulation of benzamide.
