Abstract
In the present work, an innovative biocompatible heterogeneous organo-nanocatalyst is prepared based on the grafting of arginine amino acid on the channels and pores of dendritic fibrous nano silica (DFNS). The designed organo-nanocatalyst (KCC-1-nPr-NH-Arg) was characterized by using Field emission scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FT-IR), energy dispersive X-ray spectroscopy (EDS), map analysis, and adsorption/desorption (BET-BJH) instruments. The results of analysis shown that the engineered catalyst has uniform fibrous spheres and dendritic structure with high surface area (178 m2 /g) and great pore volume (0.35 cm3 .g-1 ). Because of exceptional dendritic structure of the engineered organo-nanocatalyst, the active sites are available and the dispersion and adsorption capacity of the reagents and products increase in the pores and channels of the catalyst. Hence, KCC-1-nPr-NH-Arg was used as an capable heterogeneous basic nanocatalyst in the synthesis of 1,8-dioxo decahydroacridine derivatives from the one-pot four component reactions of aromatic aldehydes, dimedone, and ammonium acetate in solvent free conditions with shorter reaction times (13-35 min) and higher yields (94-98%) in evaluation with other reported works. It is expected that, the engineered green organo-nanocatalyst can be used to synthesize other organic compounds. This article is protected by copyright. All rights reserved.
