Solvent-free synthesis of amidoalkyl naphthols in the presence of MWCNTs@SiO2/SO3H as effective solid acid catalyst

Abstract: Multiwalled carbon nanotubes (MWCNTs) were modified with sulfonic acid groups through a new method. In the first step, MWCNTs’ surfaces were hydroxylated using KMNO4 as oxidating agent and a surfactant (TPABr). Second, SiO2

One-pot three-component synthesis of 1-amidoalkyl naphthols and polyhydroquinolines using a deep eutectic solvent: a green method and mechanistic insight

The multicomponent synthesis of 1-amidoalkyl naphthols and polyhydroquinolines has been developed as an atom-economic procedure catalyzed by a deep eutectic solvent ([CholineCl][ZnCl2]3). The reactions proceed smoothly at low temperatures for a short reaction time without the use of toxic and volatile organic solvents. Deep eutectic solvents are capable of not only allowing multicomponent reactions to proceed in high yield but also controlling the selectivity towards desired products. The mechanistic insight was examined by HRMS (ESI) to propose a plausible mechanism. Furthermore, [CholineCl][ZnCl2]3can be recycled in up to three consecutive cycles with an insignificant loss of catalytic activity under the optimized conditions.

2-Hydroxy-5-sulfobenzoic acid: An efficient organocatalyst for the three-component synthesis of 1-amidoalkyl-2-naphthols and 3,4-disubstituted isoxazol-5(4H)-ones

2-Hydroxy-5-sulfobenzoic acid (2-HSBA) efficiently catalyzed the one-pot three-component synthesis of a wide variety of 1-amidoalkyl-2-naphthols and 3,4-disubstituted isoxazol-5(4H)-ones. The three-component process of substituted benzaldehydes, 2-naphthol, and amides (benzamide and acetamide) or urea occur using 10 mol% of 2-HSBA as an organocatalyst under solvent-free reaction conditions (SFRCs) at 100 °C. It was also found that the best results for the preparation of 3,4-disubstituted isoxazol-5(4H)-ones were achieved using 15 mol% of 2-HSBA under aqueous conditions at room temperature. The reactions are easy to do and were completed within 3-25 min (for amidoalkyl naphthols), and 70-120 min (for 3,4-disubstituted isoxazol-5(4H)-ones), while the expected products were obtained in 82-97 % yields. The catalyst can be recovered and reused several times in the template reactions. This procedure offers the advantages of convenience, simple operational procedure, cost-effectiveness, no use of hazardous organic solvents, and the commercial availability of the catalyst.
