Synthetic Route of 554-62-1, As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. 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 article, author is Lin, Ye, introduce new discover of the category.
A remote cascade asymmetric inverse-electron-demand oxa-Diels-Alder reaction of allyl ketones with isatin-derived beta,gamma-unsaturated alpha-keto esters has been developed in the presence of a chiral bifunctional squaramide catalyst. Taking advantage of the secondary amide activating group, a series of enantioenriched 3,4′-pyranyl spirooxindole derivatives bearing three contiguous chiral centers were attained in high yields (84 to >99%) with excellent enantioselectivities (96-99% ee). Moreover, the gram-scale synthesis and the construction of 1-benzazepine scaffold by the product were also demonstrated.
Synthetic Route of 554-62-1, 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 554-62-1 is helpful to your research.
