title: Concise synthesis of 2, 3-diarylpyrimido[1,2-a]benzimidazole based on isoflavones.
abstract: The 2,3-diarylpyrimido[1,2-a]benzimidazole derivatives were prepared by one-step cyclocondensation of 2-aminobenzimidazole with isoflavone in methanol. Single-crystal diffraction analysis was performed for 2-(2-hydroxyl-4-isopropoxy-phenyl)-3-phenylpyrimido[1,2-a]benzimidazole. The fluorescence properties of the fused 2, 3-diarylpyrimido[1, 2-a]benzimidazole were evaluated.
