The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.21436-03-3, Name is (1S,2S)-Cyclohexane-1,2-diamine, molecular formula is C6H14N2. In a Article，once mentioned of 21436-03-3, SDS of cas: 21436-03-3
Designing novel catalytic system for efficient synthesis of enantiomerically pure beta-hydroxy nitroalkanes is a challenging area of research. Herein, we have designed a chiral heterogeneous catalyst through the successful loading of chiral Cr(III)-salen complex over sulfonic acid functionalized SBA-15 material. The catalyst has been thoroughly characterized by powder XRD, N2 adsorption/desorption, XPS, HR-TEM, CHN, AAS analyses and FT-IR spectroscopy. The reactivity of the catalyst has been examined in the enantioselective Henry reaction, where different substituted aromatic, heteroaromatic as well as aliphatic aldehydes produced corresponding beta-hydroxy nitroalkanes with excellent product yields (up to 90%) and enantioselectivities (up to 91%). Moreover, this protocol has also been employed as the key-step to prepare enantiomerically pure drug (R)-(-)-isoproterenol from 3,4-dimethoxybenzaldehyde.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 21436-03-3 is helpful to your research., SDS of cas: 21436-03-3
