The main demerit of using strong acid for catalyzing amidoalkyl-naphthol synthesis results in some disadvantages. Because of the use of acidic catalysts in most of the reported methods, application of aldehydes bearing basic groups or acid-sensitive aldehydes in the reaction is not possible. Polyphenolic nature of tannic acid may be explored for their catalytic efficiency. Its weak acidity (pKa around 6) is due to the numerous phenol groups in the structure. Because of their controlled reducing property and optimum hydrogen donor’s capability, it may be used as a mild catalyst where strong Bronsted acids are found detrimental. We have earlier explored the catalytic ability of tannic acid for the synthesis of 1,5-benzodiazepines with promising results (Sandhar et al., 2012). Tannic acid was found to be non-toxic, cheap and efficient catalyst for that particular reaction. Herein, we have investigated the potential of tannic acid as a catalyst for the synthesis of 1-amidoalkyl-2-naphthol derivatives via one-pot multi-component condensation reactions without solvent by various green chemistry methods (Method A, B and C) ( Scheme 1).
