Abstract

This article addresses new developments in silver-catalyzed cyclization processes, resulting in the formation of carbocyclic or heterocyclic rings. Some essential techniques in organic chemistry include silver-catalyzed reactions. In addition, silver catalysts have been emerged as a novel catalysis in the last two decades. In these sequences, preparations of oxygen and nitrogen-containing heterocyclic compounds emerge as the most important development of new methodology. Silver catalysts exhibit significant reactivity in mild conditions in contrast to other transition metals such as copper, lead, zinc, ruthenium, gallium, indium, and niobium. These developments have lots of scientific attention due to their potential to synthesise of heterocyclic compounds in medicinal and agrochemical use. This current literature review summarises several silver-catalyzed oxo and aza-cyclization processes using readily available starting materials.
