5-Isopropyl-1,3-cyclohexanedione is a cyclic 1,3-diketone. It can be prepared by condensation of isobutylideneacetone with ethyl malonate. 5-Isopropyl-1,3-cyclohexanedione on methylation with methyl iodide yields 5-isopropyl-2-methyl-1,3-cyclohexanedione. A multistep-synthesis of 5-isopropyl-1,3-cyclohexanedione involving aldol condensation, Dieckmann-type annulation, ester hydrolysis and decarboxylation is reported. |
