The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6. Recommanded Product: 100-51-6
We recently developed a novel chiral N-heterocyclic carbene (NHC) catalyzed dynamic kinetic enantioselective acylation (DKEA) and dynamic kinetic diastereoselective acylation (DKDA) of Achmatowicz rearrangement products to generate useful intermediates for the further synthesis of carbohydrates. In this update, we describe a divergent NHC catalytic strategy for the stereoselective preparation of all four isomers starting from a common racemic precursor. The present report provides easy access to diverse optically pure dihydropyranones.
Recommanded Product: 100-51-6. About Benzyl Alcohol, If you have any questions, you can contact Zhao, CG; Wang, J or concate me.
