Abstract
6-Alkoxycarbonylmethyl-4H-1,3-dioxin-4-one derivatives are produced by reacting a 6-halomethyl-4H-1,3-dioxin-4-one derivative with carbon monoxide and an alcohol or water, and 3-oxopentanedicarboxylic acid esters are further produced by reacting the above derivatives with an alcohol or water. Such a process can produce 3-oxopentanedicarboxylic acid esters in an easy and simple and efficient manner.
