Preparation of arginine-glutaric acid-based-deep eutectic solvent and its application as a potent catalyst for the synthesis of pyranopyrimidines

Scientific Reports
A new natural deep eutectic solvent (DES) based on arginine (ARG) and glutaric acid (GLU) was prepared. The eutectic point phase diagram showed that the best ratio for preparation of ARG/GLU-DES is one mole of ARG to three moles of GLU. Then, the new DES
