Abstract: A photoredox-catalysed chlorination of quinoxalin-2(1H)-ones was developed by using CHCl3 as a chlorine source, thus affording various 3-chloroquinoxalin-2(1H)-ones in moderate to high yields. This protocol is characterized by mild reaction conditions, excellent regioselectivity, and readily…

Abstract: Reduction of C = N double bond is the most important phase I metabolism process of quaternary benzophenanthridine alkaloids (QBAs). Inspired by the NADPH mediated reduction in QBAs, a visible-light promoted reductive aminomethylation of QBAs for synthesis…
