An improved efficient synthesis of new N-heterocylic, homocyclic and aliphatic dronic acids

Abstract

Abstract New N-heterocylic, homocyclic and aliphatic dronic acids were synthesized through an improved facile and versatile route by the reaction of various carboxylic acids with Phosphorus trichloride (PC), phosphorus acid (PA) and methanesulfonic acid under reflux and inert atmosphere. Representatively, the dronic acid derived from stearic acid as a long chained fatty acid was also synthesized. All the obtained compounds were analyzed and characterized by means of FT IR, 1H, 13C and 31P NMR spectroscopic techniques. In addition, the compound derived from stearic acid was characterized by means of FT IR and Mass spectrometry due to its insolubility in D2O and DMSO-d 6. GRAPHICAL ABSTRACT
