Electric Literature of 344-25-2, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 344-25-2, name is H-D-Pro-OH. In an article，Which mentioned a new discovery about 344-25-2
The glycine fragment in the nickel(II) complex (1) formed from the Schiff’s base of glycine and (S)-o-<(N-benzylprolyl)amino>benzophenone (2) undergoes base-catalysed Michael addition to acrylaldehyde, alpha-methylacrylaldehyde, (E)-crotonaldehyde, (E)-cinnamaldehyde, and methyl vinyl ketone.No products of 1,2-addition were found in the Et3N-catalysed reactions.Addition followed by epimerization of the isomeric complexes proceeds with high diastereoselectivity at Calpha (90percent) and Cbeta of the corresponding amino acid side chains.After chromatographic separation, the diastereoisomerically pure complexes were decomposed and the resulting dihydropyrrole-2-carboxylic acids reduced with NaBH3CN to give (S)-proline, trans-3-methyl-(S)-proline, trans-5-phenyl-(S)-proline, and a mixture of cis- and trans-5-methyl-(S)-prolines.The chiral auxiliary (2) was recovered in 80-90percent yield.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.344-25-2. In my other articles, you can also check out more blogs about 344-25-2
