Abstract
A 6-aminocarbonylmethyl-4H-2,3-dioxin-4-one compounds can be produced by reacting a 6-halomethyl-4H-2,3-dioxin-4-one compound with a primary or secondary amine and carbon monoxide. The reaction may be carried out in the presence of a catalyst comprising a platinum group metal. 3-oxopentanedicarboxylic acid monoamides and 3-oxopentanedicarboxylic acid amide esters can be are produced by reacting 6-aminocarbonylmethyl-4H-2,3-dioxin-4-one compound with an alcohol or water. Using such intermediates, 6-aminocarbonylmethyl-4H-2,3-dioxin-4-one compound, 3-oxopentanedicarboxylic acid amide esters can provide in an easy and simple and efficient manner.
