History of Heterocyclic Chemistry

The history of heterocyclic chemistry began in the 1800s, in step with the development of organic chemistry. Some noteworthy developments:
1818: Brugnatelli isolates alloxan from uric acid
1832: Dobereiner produces furfural (a furan) by treating starch with sulfuric acid
1834: Runge obtains pyrrole ("fiery oil") by dry distillation of bones
1906: Friedlander synthesizes indigo dye, allowing synthetic chemistry to displace a large agricultural industry
1936: Treibs isolates chlorophyl derivatives from crude oil, explaining the biological origin of petroleum.
1951: Chargaff's rules are described, highlighting the role of heterocyclic compounds (purines and pyrimidines) in the genetic code.

Famous quotes containing the words history of, history and/or chemistry:

    The history of every country begins in the heart of a man or a woman.
    Willa Cather (1876–1947)

    I believe that history has shape, order, and meaning; that exceptional men, as much as economic forces, produce change; and that passé abstractions like beauty, nobility, and greatness have a shifting but continuing validity.
    Camille Paglia (b. 1947)

    If thought makes free, so does the moral sentiment. The mixtures of spiritual chemistry refuse to be analyzed.
    Ralph Waldo Emerson (1803–1882)
