One-Pot Chemoenzymatic Conversion of Alkynes to Chiral Amines ACS Catalysis (IF13.084), Pub Date : 2021-09-29, DOI: 10.1021/acscatal.1c03474 Sam Mathew, Arunachalam Sagadevan, Dominik Renn, Magnus Rueping
A one-pot chemoenzymatic sequential cascade for the synthesis of chiral amines from alkynes was developed. In this integrated approach, just ppm amounts of gold catalysts enabled the conversion of alkynes to ketones (>99%) after which a transaminase was used to catalyze the production of biologically valuable chiral amines in a good yield (up to 99%) and enantiomeric excess (>99%). A preparative scale synthesis of (S)-methylbenzylamine and (S)-4-methoxy-methylbenzylamine from its alkyne form gave a yield of 59 and 92%, respectively, with ee > 99%.
