| Summary: | A new, facile, cost-effective and environment-friendly protocol is reported for the synthesis of 1-amidoalkyl-2-naphthols exploring tannic acid as a novel, cheap and biodegradable catalyst. β-naphthol is condensed with substituted aromatic aldehydes and various amides using catalytic amount of tannic acid in the absence of solvent under thermal (hot plate and oil bath) and microwave irradiation techniques. This green protocol offers many advantages such as short reaction time, use of environment-friendly and cheap catalyst and good to excellent yields. |
