“…[18] A structure of ring fused with quinoxalines displays diverse pharmacological activities and has found applications in dyes, electron luminescent materials, and chemically controllable switches, as building blocks for the synthesis of anion receptors, cavitands, dehydroannulenes, and organic semiconductors, and as electrontransport materials in multilayer OLEDs. [25][26][27][28][29][30][31][32][33][34][35] Recently, Chen et al have reported a threecomponent domino reaction of HKAs with arylglyoxal monohydrates and β-diketone (like cyclohexane-1,3diones and 1,3-diphenylpropane-1,3-dione) for the synthesis of fused pyrroles. [20][21][22][23] To date, many works focus on the development of novel, MCRs, for constructing diverse and highly substituted fused heterocycles from available synthons heterocyclic ketene aminals (HKAs) with advantage for synthetic chemistry.…”
