A practical methodology for the visible-light induced decarboxylative alkylation of quinoxalin-2(1H)-ones was developed using commercially available and cheap carboxylic acids as alkylating reagents. The reaction is performed without the need for a metal catalyst, acid or basic additive, or external photosensitizer, making it an environmentally friendly and attractive protocol for the alkylation of quinoxalines.
Using commercially available and cheap carboxylic acids as alkylating reagents, a practical methodology for the visible-light induced decarboxylative alkylation of quinoxalin-2(1H)-ones was developed. The reaction proceeds in the absence of metal-catalyst, acid or basic additive, or external photosensitizer, making it an environmentally friendly and attractive protocol for the alkylation of quinoxalines.
