In this study, new derivatives of aminoanthraquinone were synthesized efficiently via a one-pot three-component condensation reaction, yielding the desired products in short time with good to excellent yields. The chemical structures of the synthesized products were confirmed using various analytical techniques.
In this study, new derivatives of aminoanthraquinone have been synthesized via one-pot three-component condensation reaction of 1- and 2-amino anthraquinones, triethyl orthoformate and CH-acid compounds without using any solvent or catalyst in mild temperature (50 degrees C). This simple and efficient method yields the desired products in short reaction time (14-50 min) and good to excellent yields (85-96%). Moreover, chemical structures of synthesized products have been entirely confirmed by FT-IR, H-1 and (CNMR)-C-13 and mass spectroscopy and melting points.
