Abstract
This study presents a new environmentally sustainable catalytic method for the synthesis of symmetrically substituted pyridine derivatives and substituted alkene derivatives using zinc phosphate (Zn3(PO4)2·4H2O) as a non-toxic and green heterogeneous catalyst. The catalytic support was prepared by a co-precipitation method, and it was applied for the first time as a heterogeneous catalyst in organic synthesis. Trisubstituted pyridine derivatives were prepared with excellent yields (82-94%) via a three-component, one-pot synthesis of aromatic aldehydes, substituted acetophenones, and ammonium acetate in the presence of 0.4 mol% of Zn3(PO4)2·4H2O using an ethanol/water (4/1) mixture as the solvent, while substituted alkenes were synthesized with up to 90% yield using the prepared catalyst. The experimental results demonstrate the efficiency of these new catalytic syntheses that present various advantages such as short reaction times, excellent yields, and an environmentally friendly profile.

Abstract
A highly efficient one-pot method for the synthesis of 2,4,6-triaryl pyridines has been developed via cascade deamination and annulation. Copper triflate and molecular iodine easily promoted the oxidative cyclization reaction of vinyl azide and benzylamine to access a wide variety of substituted pyridine substrates under an oxygen atmosphere. The presence of benzyl amine enables the cyclization process by providing the aryl functionality and the nitrogen source. Moreover, a broad range of substrates with good functional group tolerance, avoidance of external oxidants, excellent product yields, operational simplicity and mild conditions are the notable advantages of the present protocol.

Abstract
2,4,6-Triarylpyridines are key building blocks to access functional molecules that are used in the design of advanced materials, metal-organic frameworks, supramolecules, reactive chemical intermediates and drugs. A number of synthetic protocols to construct this heterocyclic scaffold have been developed to date, the most recent of which (2015-present) are included and discussed in the present review. An emphasis has been placed on the utility of each synthetic approach in view of the scope of aryl/hetaryl substituents, limitations and an outlook of each method to be used in applied sciences.
