Aldol structural units are found in many important molecules, whether naturally occurring or synthetic. [8] [9] The reaction is well used on an industrial scale, notably of pentaerythritol, [10] trimethylolpropane, the plasticizer precursor 2-ethylhexanol, and the drug Lipitor (atorvastatin, calcium salt).

In organic chemistry, aldol reactions are acid- or base-catalyzed reactions of aldehydes or ketones. Aldol addition or aldolization refers to the addition of an enolate or enolation as a nucleophile to a carbonyl moiety as an electrophile.
An aldol condensation is a condensation reaction in organic chemistry in which two carbonyl moieties (of aldehydes or ketones) react to form a β-hydroxyaldehyde or β-hydroxyketone (an aldol reaction), and this is then followed by dehydration to give a conjugated enone.
The Mukaiyama aldol addition is a Lewis acid-mediated addition of enol silanes to carbonyl (C=O) compounds.In this reaction, compounds with various organic groups can be used (see educts). [3]

Aldols synthesized from two aldehydes are usually unstable, often producing secondary compounds such as diols, unsaturated aldehydes, or alcohols. [1] Hydroxypivaldehyde is a rare example of a distillable aldol. [3]
