Imidazolone

Imidazolinones or imidazolones are a family of heterocyclic compounds, the parents of which have the formula OC(NH)2(CH)2.

Two isomers are possible, depending on the location of the carbonyl (CO) group.

The NH groups are nonadjacent.

A common route to imidazol-2-ones involves condensation of ureas and acyloins.

[3] 4-Imidazolones arise from the condensation of amidines with 1,2-dicarbonyls such as glyoxal.

4-imidazolones are advanced glycation endproducts (AGEs), a class of modified proteins that are biomarkers for diabetes. In this drawing the imidazolone is the C 3 N 2 ring in red and black. [ 1 ]
