Facile Iodine(III)-Mediated Approach for the Regioselective Chlorination of 2-Aryl-2,3-dihydro-4(1H)-quinolones
摘要:
Oxidation of 2-aryl-2,3-dihydro-4(1H)-quinolones (1) with 1.5 equivalents of (dichloroiodo)benzene in dichloromethane at room temperature leads to regioselective chlorination, thereby offering an efficient method for the synthesis of new 2-aryl-6-chloro-2,3-dihydro-4(1H)-quinolones (3).
