Triketone

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.

Both species exist predominantly in the enol (C=CH) forms.

Tri- and polyketones are of practical importance as intermediates in the biosynthesis of polyketides.
