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.

sensors, chelating fragmentlibraries of quinoline- and benzimidazole-sulfonamides have been prepared and screened against several different zinc(II)-dependent matrix metalloproteinases (MMPs). The fragments show impressive inhibition of these metalloenzymes and preferences for different MMPs based on the nature of the chelating group. The findings show that focused chelatorlibraries are a powerful strategy

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.
