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 Zhou, Yi-Ming, introduce the new discover, HPLC of Formula: C18H39NO3.
A practical, efficient Fe(III)-BPsalan complex catalyzed asymmetric dearomative chlorination reaction of 2-hydroxy-1-naphthoates derivatives (22 examples) was developed. With readily available Fe(III)-BPsalan complex as catalyst at 5 mol% catalyst loading, various 2-hydroxy-1-naphthoates derivatives bearing different substituents were efficiently chlorinated to afford chiral naphthalenones bearing a Cl-containing all-substituted stereocenter in high yields and with good to excellent enantioselectivities under mild reaction conditions. The reaction could be conducted at gram scale with the high efficiency and selectivity retained. In addition, the reaction could be extended to asymmetric dearomative bromination to afford the corresponding brominated product in 87% yield and 76% ee.
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. HPLC of Formula: C18H39NO3.
