ABSTRACT
Due to significant biological activity associated with N-, O-, and S-heterocycles, several reports for their synthesis have appeared in recent decades. Traditional approaches require expensive or highly specialized equipment or would be of limited use to the synthetic organic chemist due to their highly inconvenient approaches. This review summarizes the applications of ruthenium metal with emphasis of their synthetic applications for oxygen-containing six-membered heterocylces. In summary, this review article describes the synthesis of heterocyclic rings containing different heteroatoms.
