Latest Patents

Paul J. Gilligan's latest patents showcase his expertise in synthesizing novel compounds with antibacterial properties. One of his notable inventions is a process for the preparation of 3-(2'-fluorophenyl)pyridine derivatives. This innovative method involves the coupling of a 2-fluorophenyl-metallic compound with a pyridyl bromide or iodide, facilitated by a transition metal catalyst, followed by nitration and hydrogenation processes. The resulting compounds are then modified by adding substituents to the nitrogen of the formed amine and cyclizing with dialkyl or dibenzyl ethoxymethylene malonate to yield 6-fluoro-7-pyridyl-1,4-dihydroquinol-4-one 3-carboxylates, which can be hydrolyzed to produce the corresponding acids. Another key advancement in his patent portfolio includes the development of 7-heterocyclic-1,4-dihydroquinolones, specifically 1-Alkyl-6,8-difluoro-7-heterocyclic-1,4-dihydroquinol-4-one 3-carboxylic acids, also with antibacterial activity. These compounds are prepared using conventional cyclization methods, reinforcing his innovative approach to drug development.
