A rapid alkenylation of quinoxalin-2(1H)-ones with ketones enabled by a combination of Mannich-type reaction and solar photocatalysis to afford 3,4-dihydroquinoxalin-2(1H)-one derivatives I [R1 = 5-Me, 5-F, 7-tBu, etc.; R2 = Me, Et, Bn, etc.; R3 = Me, Et, 2-furyl, etc.] in moderate-to-good yields was demonstrated. Control experiments illustrated that the in situ generated 1O2 played a central role in this reaction. This green and efficient strategy provided a practical solution for the synthesis of potentially bioactive compounds I that containing a 3,4-dihydroquinoxalin-2(1H)-one structure.
Chinese Chemical Letters published new progress about Alkenylation. 55687-19-9 belongs to class chlorides-buliding-blocks, and the molecular formula is C8H5ClN2O, Related Products of 55687-19-9.
