摘要：

A simple and efficient method to construct benzo[4,5]imidazo[1,2-c]quinazolin-6(5H)-one skeleton was reported. A powerful functional group transformation strategy of -NO2 transformed into -NH2 was involved in this method. Only Mo(CO)(6) was used in the reaction, which acted as both reductant and cyclization accelerator. And a series of benzo[4,5]imidazo[1,2-c]quinazolin-6(5H)-one derivatives were obtained.
