In this study, three eco-friendly, efficient, and convenient protocols have been reported for one-pot synthesis of 2,4,6-triaryl pyridine, 2-amino-3-cyanopyridine, and polyhydroquinoline derivatives using salicylic acid as a catalyst under solvent-free condition. The reported protocols offer several significant advantages such as the application of a nontoxic, neutral, and cheap catalyst, environmentally friendly conditions, the easy isolation of products by filtering, short reaction times, simple methodology, and good yields.

Chitosan, as a biopolymer, exhibits a strong affinity for complexation with suitable metal ions. Thus, it has received increased attention for the preparation of stable bioorganic-inorganic hybrid heterogeneous catalysts. Herein, a novel chitosan based vanadium oxo (ChVO) catalyst was prepared and fully characterized by several techniques such as Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), derivative thermal gravimetric (DTG), differential thermal analysis (DTA), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), high-resolution transmission electron microscopy (HRTEM), selected area electron diffraction (SAED), X-ray photoelectron spectroscopy (XPS) and inductively coupled plasma mass spectrometry (ICP-MS). The synthesized catalyst has been successfully used as a reusable catalyst in the synthesis of dihydropyridines and triarylpyridines.

An efficient and green synthesis of 2,4,6-triarylpyridines by a one-pot three-component condensation of aromatic aldehydes, substituted acetophenones, and ammonium acetate without catalyst at 130°C under solvent-free conditions is described. This method offers several advantages such as simple procedure, easy work-up, short reaction time, low cost, environmentally friendly conditions, and moderate to high yields.
