MUMBAI, India, July 7 -- Intellectual Property India has published a patent application (202511119430 A) filed by Indian Institute Of Technology Banaras Hindu University, Varanasi on November 29, 2025, for A Method Of Synthesis Of A Coumarin Derivative.
Inventors include Deepak Kumar; Harish Kumar Indurthi; Samarpita Das; Pallavi Saha; and Harshali Paliwal.
The application for the patent was published on July 03, 2026, under issue no. 27/2026.
Abstract: The present invention relates to a cost-effective and facile metal-free method of synthesis of a coumarin derivative. Moreover, the method involves metal-free synthesis of a coumarin derivative that includes production of an aminocoumarin compound through a reaction between hydroxycoumarin and a multifunctional reagent, 2-chloro-4, 6-dimethoxy-1,3,5-triazine (CDMT) under milder reaction conditions that facilitates bypassing -OTf or -ONf functionalization and halogenation reaction. Further, the present invention provides a method of synthesis of a coumarin derivative that is free of pseudohalide derivatives, thus improving the yield of coumarin derivative.
