Reeves, Jonathan T. published the artcileDevelopment of an Enantioselective Hydrogenation Route to (S)-1-(2-(Methylsulfonyl)pyridin-4-yl)propan-1-amine, COA of Formula: C6H4ClNO2, the publication is Organic Process Research & Development (2014), 18(7), 904-911, database is CAplus.
A highly enantioselective enamide hydrogenation route to the title amine was developed. Highlights of the synthesis include an efficient two-step synthesis of a 2-sulfonyl 4-pyridyl Et ketone, a simple enamide synthesis by direct condensation of propionamide with a ketone, catalytic asym. enamide hydrogenation employing the inhouse-developed ligand MeO-BIBOP, and a mild epimerization-free deprotection of a propionamide using Koenig’s procedure.
