A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, SDS of cas: 344-25-2, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 344-25-2, Name is H-D-Pro-OH, molecular formula is C5H9NO2. In a Article, authors is Cardoso, Ana Lucia，once mentioned of 344-25-2
The synthesis of chiral functionalized beta-amino esters via the hydride reductive amination of chiral allenes was explored. These compounds can be regarded as beta-peptoids building blocks bearing a chiral side chain at the nitrogen and at the same time retaining the beta-amino acid side chain. beta-Enamino esters were obtained from the nucleophilic addition of alpha-amino esters (l-Ala, d-Ala, l-Phe, l-Leu, l-Trp and d-Trp methyl esters) to 2,3-allenoates bearing a chiral auxiliary, which determines the stereochemistry outcome of the subsequent reduction reaction. It was also demonstrated that in the reduction of beta-enamino esters derived from l-Pro and d-Pro methyl esters the chirality of the new chiral center is controlled by the alpha-amino ester moiety.
Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about is helpful to your research. SDS of cas: 344-25-2
