TL;DR: Diverse new azoloazines were synthesized from the reaction of fluorinated hydrazonoyl chlorides with heterocyclic thiones, 1,8‐diaminonaphthalene, ketene aminal derivatives, and 4‐amino‐5‐triflouromethyl‐1,2,4‐triazole‐2‐thiol to predict their potential as a hopeful anti‐COVID and to investigate their binding pattern.

TL;DR: The synthesis of pyrimidine derivatives is a well-known heterocyclic compound that is commonly present in RNA and deoxyribonucleic acid (DNA) bio-isosteres as discussed by the authors.

TL;DR: In this article, the authors presented the traditional and efficient synthesis of 15 drugs that have been studied for the COVID-19 treatment, containing in their structure heterocycles like indole, quinoline, pyrimidone, tetrahydrofuran, pyrrolidine, triazole and pyrazine.

TL;DR: In this paper, the solvent and catalyst free synthesis of imidazo[1,2-a]pyridines in excellent to nearly quantitative yields from 2-aminopyridine and a wide variety of ω-bromomethylketones using a grindstone procedure at 25-30 °C for 3-5 min.
