Naphthofuran-4,9-dione derivatives exhibit a broad spectrum of biological and medicinal activities. The development of green and efficient methods for the synthesis of these heterocyclic compounds is of great importance. In this paper, the N-chloro-succinimide (NCS)-promoted reaction of 2-amino-benzo[g]chromene-3-carbonitriles or ethyl 2-amino-pyrano[3,2-c]-chromene-3-carboxylates with alcohols lead to the naphthofuran-4,9-dione or diethyl furo[3,2-c]chromene-2,2-dicarboxylate was reported. All reactions were completed in 30 min under room temperature, and two types of novel fused furan derivatives were obtained in 48%~97% yields under tandem ring-opening/cyclization processes.

Key words: naphthofuran-4,9-dione, NCS, domino reaction, heterocyclic
