5-ISOPROPYL-1,3-CYCLOHEXANEDIONE Usage And Synthesis

Uses

5-Isopropyl-1,3-cyclohexanedione may be used as starting reagent for the synthesis of carvotanacetone analogs. It may be used in the preparation of monocyclic terepenes. It may be used in the synthesis of 2H-pyrans, via reaction with α,β-unsaturated aldehydes.

General Description

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.
