Weis, Erik published the artcileIridium-catalyzed C-H methylation and d3-methylation of benzoic acids with application to late-stage functionalizations, Safety of 3-(Methoxycarbonyl)benzoic acid, the publication is iScience (2021), 24(5), 102467, database is CAplus and MEDLINE.
An iridium-catalyzed carboxylate-directed ortho C-H methylation and d3-methylation of benzoic acids was reported. The method used com. available reagents and precatalyst and requires no inert atm. or exclusion of moisture. Substrates bearing electron-rich and electron-poor groups were successfully methylated, including compounds with competing directing/coordinating groups. The method was also applied to the LSF of several marketed drugs, forming analogs with increased metabolic stability compared with the parent drug.
