Abstract
In the reaction between γ-chloro-δ-hydroxy-γ-valerolactone and potassium phthalimide in dimethylformamide, γ-phthalimido-δ-hydroxyγ-valerolactone is formed, alkaline hydrolysis of which gives δ-hydroxylevulinic acid. It is shown that oxidation of di(β-chloroallyl)malonic acid with hydrogen peroxide in acetic acid gives the dilactone of bis(δ-hydroxy-γ-chloro-γ-hydroxy)malonic acid.
