Tropolones are of interest in their chemical and physical properties as one of the fundamental non-benzenoid aromatic compounds. Of them, 3-acetyltropolone is very useful starting material for synthesis of heterocycle-fused tropoid compounds, because it has a reactive acetyl group and β -diketone structure. This article provides a summary of synthesis of heterocycle-fused tropoid compounds from 3-acetyl-, 3-(2-bromoaoetyl)-, and 3-cinnamoyltropolones. The latter two compounds were derived from 3-acetyltropolone.
