Abstract: An eco-friendly and efficient straightforward method has been developed for the synthesis of ethyl 3-amino-1-aryl-1H-benzo[f]chromene-2-carboxylate derivatives via 1,4-diazabicyclo[2.2.2]octane (DABCO)-catalysed cyclisation of β-naphthol and 3-aryl-2-cyanoacrylates using water as a green solvent. All products precipitated from the… read more here.
