A series of quinolino[3,4-b] quinoxalin-6(5H)-ones have been synthesized using an Ugi/deprotection/cyclization (UDC) strategy, followed by a nucleophilic aromatic substitution reaction. This facile microwave-assisted method provided good yields and could potentially be used for the construction of a diverse library of quinolino[3,4-b] quinoxalin-6(5H)-ones for high-throughput screening in medicinal chemistry.
