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. Recommanded Product: 1273-94-5. In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. Introducing a new discovery about 1273-94-5, Name is 1,1′-Diacetylferrocene
Due to using (R)- or (S)-alpha-methylbenzylamine as a chiral auxiliary, and low-temperature regime for reduction of the intermediate ferrocenyl-mono- or 1,1?-bis-ketimines, the corresponding secondary mono- or 1,1?-bis-amines were prepared with high diastereoselectivity. Removal of the alpha-methylbenzyl group afforded the optically active primary mono- and bis-ferrocenylethylamines in high yields. The absolute configuration of (R,R)-3a and (S,S)-3b was determined by X-ray single crystal diffraction. We have developed an efficient and highly stereoselective synthesis of the chiral mono- and bis-ferrocenylamines via sodium borohydride reduction, followed by reductive cleavage of the alpha-methylbenzyl moiety using 5% Pd/C and HCOONH 4. The selectivity was up to 99% de. Copyright
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis. We will look forword to the important role of 1273-94-5, and how the biochemistry of the body works.Recommanded Product: 1273-94-5
