Abstract: Herein, a photoinitiated radical relay reaction of quinoxalin-2(1H)-ones, with acyloxy nitroso compounds as a source of radicals, is described. Although the C-H functionalization of quinoxalin-2(1H)-ones has been investigated, its difunctionalization, the simultaneous construction of C-C… read more here.

Abstract: We present an organophotoredox-catalyzed direct Csp3-H alkylation of 3,4-dihydroquinoxalin-2-ones employing N-(acyloxy)pthalimides to provide corresponding products in good yields. A broad spectrum of NHPI esters (1°, 2°, 3°, and sterically encumbered) participates in the photoinduced alkylation… read more here.
