Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 554-62-1, Name is Phytosphingosine, SMILES is CCCCCCCCCCCCCC[C@@H](O)[C@@H](O)[C@@H](N)CO, belongs to chiral-catalyst compound. In a document, author is Kwok, Timothy, introduce the new discover, COA of Formula: C18H39NO3.
Hydrogen-borrowing catalysis represents a powerful method for the alkylation of amine or enolate nucleophiles with non-activated alcohols. This approach relies upon a catalyst that can mediate a strategic series of redox events, enabling the formation of C-C and C-N bonds and producing water as the sole by-product. In the majority of cases these reactions have been employed to target achiral or racemic products. In contrast, the focus of this Minireview is upon hydrogen-borrowing-catalysed reactions in which the absolute stereochemical outcome of the process can be controlled. Asymmetric hydrogen-borrowing catalysis is rapidly emerging as a powerful approach for the synthesis of enantioenriched amine and carbonyl containing products and examples involving both C-N and C-C bond formation are presented. A variety of different approaches are discussed including use of chiral auxiliaries, asymmetric catalysis and enantiospecific processes.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 554-62-1 is helpful to your research. COA of Formula: C18H39NO3.
