Enantioselective Hydrogenation of Imidazo[1,2-a]pyridines was written by Schlepphorst, Christoph;Wiesenfeldt, Mario P.;Glorius, Frank. And the article was included in Chemistry – A European Journal in 2018.Quality Control of (6-Aminopyridin-2-yl)methanol This article mentions the following:
The enantioselective synthesis of tetrahydroimidazo[1,2-a]pyridines by direct hydrogenation was achieved using a ruthenium/N-heterocyclic carbene (NHC) catalyst. The reaction forgoes the need for protecting or activating groups, proceeds with complete regioselectivity, good to excellent yields, enantiomeric ratios of up to 98:2, and tolerates a broad range of functional groups [e.g., I → II (95.5:4.5 e.r., 99% isolated yield)]. 5,6,7,8-Tetrahydroimidazo[1,2-a]pyridines, which are found in numerous bioactive mols., were directly obtained by this method, and its applicability was demonstrated by the (formal) synthesis of several functional mols. In the experiment, the researchers used many compounds, for example, (6-Aminopyridin-2-yl)methanol (cas: 79651-64-2Quality Control of (6-Aminopyridin-2-yl)methanol).
(6-Aminopyridin-2-yl)methanol (cas: 79651-64-2) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Quality Control of (6-Aminopyridin-2-yl)methanol
