Nimje, Roshan Y. published the artcileDevelopment of a Stereoselective and Scalable Synthesis for the Potent Indoleamine 2,3-Dioxygenase 1 (IDO1) Inhibitor, BMT-297376; N-((R)-1-((cis)-4-(3-(Difluoromethyl)-2-methoxypyridin-4-yl)cyclohexyl)propyl)-6-methoxynicotinamide, Quality Control of 343338-28-3, the main research area is difluoromethyl methoxypyridinyl cyclohexyl methoxynicotinamide preparation enantioselective indoleamine dioxygenase inhibitor.
The current work describes a stereoselective and scalable route to N-((R)-1-((cis)-4-(3-(difluoromethyl)-2-methoxypyridin-4-yl)cyclohexyl)propyl)-6-methoxynicotinamide I from readily available 1,4-dioxaspiro[4.5]decan-8-one. The developed process encompasses an efficient 1,4-trans-selective synthesis of (trans)-4-(3-(difluoromethyl)-2-methoxypyridin-4-yl)cyclohexyl methanesulfonate as the key intermediate and the use of Ellman sulfinamine methodol. to install an alkyl amine in a stereoselective manner. Various synthetic routes were screened to accomplish a stereoselective and scalable protocol to access the title compound I. This advancement enabled a competent route to the title compound in an enantioselective, safe, cost-effective, and scalable manner.
