  • Title: Furans, thiophenes and related heterocycles in drug discovery.
    Author: Sperry JB, Wright DL.
    Journal: Curr Opin Drug Discov Devel; 2005 Nov; 8(6):723-40. PubMed ID: 16312148.
    Abstract:
    The five-membered aromatic heterocycles containing oxygen and sulfur are key building blocks used in medicinal chemistry applications. Furans, thiophenes and related azole analogs constitute an important class of compounds that are readily available, stable and easily functionalized. In this review, the authors survey the recent literature and highlight the application of such compounds in the development of therapeutic agents. This review focuses on two major strategies involving these compounds. The first is the use of these rings as intact scaffolds within the final target compound, and the second is the use of these compounds as convenient and flexible synthons for non-aromatic structural moieties.
