ABSTRACT
A photocatalytic three-component cascade reaction of quinoxalin-2(1H)-ones, alkenes, and sulfinic acids under metal-, strong oxidant-, and external photocatalyst-free conditions was developed. The reaction was performed at room temperature using air as a green oxidant. Various sulfonated quinoxalin-2(1H)-ones were obtained in satisfactory yields with good functional group compatibility. The preliminary study showed that the current transformation was enabled by the formation of an electron donor-acceptor (EDA) complex between quinoxalin-2(1H)-ones and sulfinic acids.
