Photoinduced and N-bromosuccinimide-mediated cyclization of 2-azido-N-phenylacetamides
An efficient synthesis of quinoxalin-2(1H)-ones or spiro[cyclohexene-1, 2?-imidazol]-4?-ones has been achieved in moderate to high yields by the visible light-induced and N-bromosuccinimide-mediated cyclization reaction of 2-azido-N-phenylacetamides at ambient temperature. Both the regioselectivity and the speed of cyclization are affected by the substituents attached to the phenyl ring. For example, quinoxalin-2-ones are produced as the main products when the substrates bear electron-withdrawing groups at the para-position of the phenyl ring; in contrast, spiro[cyclohexene-1,2?-imidazol]-4?-ones are obtained as the main products when the substrates bear electron-donating groups at the para-position.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 33282-15-4
