HCID 238498Ethyl 3-oxohexanoateYield 72%

Procedure

The 5-butyl-2,2-dimethyl-1,3-dioxane-4,6-dione thus obtained was allowed to reflux in ethanol for 2 hours, and then concentrated under reduced pressure. The resulting residue was purified using silica gel chromatography (developing solvent: n-hexane/ethyl acetate=8/2) to obtain the ethyl 3-oxohexanoate shown by the formula below.
