What is aldol reaction?

  • (noun): A reaction of aldehydes resulting in an aldol.

Aldol Reaction

The aldol reaction is a powerful means of forming carbon–carbon bonds in organic chemistry. Discovered independently by Charles-Adolphe Wurtz and Alexander Borodin in 1872, the reaction combines two carbonyl compounds (the original experiments used aldehydes) to form a new β-hydroxy carbonyl compound. These products are known as aldols, from the aldehyde + alcohol, a structural motif seen in many of the products. Aldol structural units are found in many important molecules, whether naturally occurring or synthetic. For example, the aldol reaction has been used in the large-scale production of the commodity chemical pentaerythritol and the synthesis of the heart disease drug Lipitor (atorvastatin).

Famous quotes containing the word reaction:

    Sole and self-commanded works,
    Fears not undermining days,
    Grows by decays,
    And, by the famous might that lurks
    In reaction and recoil,
    Makes flames to freeze, and ice to boil.
    Ralph Waldo Emerson (1803–1882)
