A Safe Scalable Process for Synthesis of 4,6-Bis(nitroimino)-1,3,5-triazinan-2-one (DNAM)

Autor: Raja Duddu, John H. Hoare, Reddy Damavarapu

Publikováno v: Organic Process Research & Development. 20:683-686

A modified and safe nitration process for production of 4,6-bis(nitroimino)-1,3,5-triazinan-2-one (DNAM), a high density high energy material, from melamine is described. Key to our strategy is to generate acetyl nitrate at 30–35 °C in the presenc

Chorismate mutase-catalyzed reaction of (±)-chorismic acid

Autor: John H. Hoare, Glenn A. Berchtold

Publikováno v: Biochemical and Biophysical Research Communications. 106:660-662

Chorismate mutase-prephenate dehydrogenase from E. coli and chorismate mutase from S. aureofaciens do not catalyze the conversion of (+)-chorismate (unnatural enantiomer) to prephenate. (+)-Chorismate does not inhibit the isomerization of (−)-chori
