In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 876-72-2, name is 4-Chloroindole-3-carbaldehyde, introducing its new discovery. Computed Properties of C9H6ClNO

An efficient and practical synthesis of (S)-rivastigmine intermediate was developed by employing a chemoenzymatic step toward the synthesis of chiral intermediate N-ethyl-N-methyl-carbamic acid-3-(1S-hydroxy-ethyl)-phenyl ester (2) using crude alcohol dehydrogenase from baker’s yeast with reduced nucleotide adenosine dinucleotide (NADH) as proton donor has been demonstrated.

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 876-72-2 is helpful to your research. Computed Properties of C9H6ClNO

Improved chemoenzymatic asymmetric synthesis of (S)-Rivastigmine

(S)-Rivastigmine [(S)-1] was obtained via a four-step synthesis using an asymmetric enzymatic transamination protocol as the key step. An early introduction of the carbamate pharmacophore side chain avoided the use of protective group strategies and hence led to a considerable shortcut. This strategy required a novel omega-transaminase from Paracoccus denitrificans, which could transform the highly polar key substrate 3-acetylphenyl ethyl(methyl)carbamate (4) to the corresponding amine (S)-5 in 99% ee and >80% conversion.
