Chemistry:Triketone
From HandWiki
Short description: Organic compounds with three C=O groups
In organic chemistry, a triketone or trione is an organic compound containing three ketone (>C=O) groups. The simplest triketones, such as cyclopropanetrione and 2,3,4-pentanetrione, are only of occasional theoretical interest. More pertinent are triacetylmethane and 2,4,6-heptanetrione. Both species exist predominantly in the enol (C=CH) forms.
Occurrence and significance
Tri- and polyketones are of practical importance as intermediates in the biosynthesis of polyketides.[1] These natural products are a major source of antibiotics.
Biosynthesis of orsellinic acid from polyketide intermediate.
