Catalysts and their uses in one-pot diastereoselective synthesis of remdesivir

Disclosed herein are novel catalysts for producing remdesivir in one-pot manner, in which a diastereomerically enriched form of an intermediate, which following acidic hydrolysis would give rise to the desired remdesivir, was produced with the aid of the disclosed novel catalysts. Also disclosed herein is an improved process for the preparation of remdesivir without the need to separate one of the enantiomers while minimizing the formation of undesired isomers, thus offers economic advantages for operation on a commercial scale.
