Filed:

Jan 12, 2017

Appl. No.:

15/404900

Inventors:

- Marietta GA, US
David Rembert Glass - Santa Fe NM, US
Nathan Philip Martinez - Santa Fe NM, US

International Classification:

C07C 231/14

Abstract:

A synthesis method comprises opening an anhydride to a 4-carbon acid-amide, removing ethanol soluble products, treating the resulting 4-amino-2-methylene-4-oxo-butanoic acid with Ozone in water, and evaporating the ozonolysis products to synthesize 4-amino-2,4-dioxobutanoic acid.

International Classification:

C07C 227/06

US Classification:

562567

Abstract:

A process for synthesizing 4-amino-2,4-dioxobutanoic acid involves reacting diethyl oxalate with sodium ethoxide in ethanol to form a reaction mixture, and afterward adding 2-cyano-3-hydroxy-butenedioate to the reaction mixture and allowing a reaction to proceed under conditions suitable to form a first reaction product of the formula diethyl-2-cyano-3-hydroxy-butenedioate, and then isolating the cyano-3-hydroxy-butenedioate, and afterward reacting the diethyl-2-cyano-3-hydroxy-butenedioate with aqueous sodium hydroxide under conditions suitable to form 4-amino-2,4-dioxobutanoic acid.
