Recommanded Product: (R)-Ethyl 4-chloro-3-hydroxybutanoate. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: (R)-Ethyl 4-chloro-3-hydroxybutanoate, is researched, Molecular C6H11ClO3, CAS is 90866-33-4, about Stereoselective ketone reduction by a carbonyl reductase from Sporobolomyces salmonicolor. Substrate specificity, enantioselectivity and enzyme-substrate docking studies. Author is Zhu, Dunming; Yang, Yan; Buynak, John D.; Hua, Ling.
In our effort to search for effective carbonyl reductases, the activity and enantioselectivity of a carbonyl reductase from Sporobolomyces salmonicolor have been evaluated toward the reduction of a variety of ketones. This carbonyl reductase (SSCR) reduces a broad spectrum of ketones including aliphatic and aromatic ketones, as well as α- and β-ketoesters. Among these substrates, SSCR shows highest activity for the reduction of α-ketoesters. Aromatic α-ketoesters are reduced to (S)-α-hydroxy esters, while (R)-enantiomers are obtained from the reduction of aliphatic counterparts. This interesting observation is consistent with enzyme-substrate docking studies, which show that hydride transfer occurs at the different faces of carbonyl group for aromatic and aliphatic α-ketoesters. It is worthy to note that sterically bulky ketone substrates, such as 2′-methoxyacetophenone, 1-adamantyl Me ketone, Et 4,4-dimethyl-3-oxopentanoate and Et 3,3-dimethyl-2-oxobutanoate, are reduced to the corresponding alcs. with excellent optical purity. Thus, SSCR possesses an unusually broad substrate specificity and is especially useful for the reduction of ketones with sterically bulky substituents.
