In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Cerium salts in the oxidative free radical reactions between 2-amino-1,4-naphthoquinones and β-dicarbonyl compounds, published in 2002-09-16, which mentions a compound: 18362-64-6, Name is 2,6-Dimethyl-3,5-heptanedione, Molecular C9H16O2, Category: thiazole.
The oxidative free radical reactions between 2-amino-1,4-naphthoquinones and β-dicarbonyl compounds mediated by cerium(IV) salts are described. In contrast to those mediated by manganese(III) acetate, the cerium(IV) mediated free radical reaction provides a novel method for the synthesis of benzo[f]indole-4,9-diones exclusively. This high selectivity is due to the strong oxaphilicity of the cerium salts.
Although many compounds look similar to this compound(18362-64-6)Category: thiazole, numerous studies have shown that this compound(SMILES:CC(C)C(CC(C(C)C)=O)=O), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
