Latest Patents
Eymard holds a patent for a process that involves the preparation of N-acyl derivatives of 5-aminolevulinic acid. The invention details a method where 5-hydroxymethyl furfural is condensed with a nitrile in an acid solution. The resulting N-acyl-aminomethyl furfural compound is then converted through photooxidation into N-acyl-5-aminomethyl-5-hydroxydihydro-2,5-furan-2-one. This compound is subsequently reduced with zinc in acetic acid under ultrasonic treatment to yield N-acyl-5-aminolevulinic acid. The process culminates in the production of the hydrochloride of the free acid through acid hydrolysis.
