the microwave irradiation protocol under closed vessel conditions (80 °C). The nitro-substituted rosamine was further converted into the corresponding amino derivativethrough Pd/C-catalysed hydrogenation. The syntheticprotocol used for rosamines was also successfully employed to synthesise naphthyl analogues by using 1- and 2-naphthaldehyde. In the latter case, a novel hydroxy analogue was also obtained
