Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: N-((1S,2S)-2-Amino-1,2-diphenylethyl)-2,3,4,5,6-pentafluorobenzenesulfonamide, is researched, Molecular C20H15F5N2O2S, CAS is 313342-24-4, about Communications: High-throughput screening of enantioselective catalysts by immunoassay.Application of 313342-24-4.
Immunoassay techniques are demonstrated for anal. of catalytic activity of a combinatorial library of enantioselective reduction catalysts. By using an antibody that binds indiscriminately to the two enantiomers of the reduction product, the yield of the reaction can be calculated, and subsequently employing an enantiospecific antibody the enantiomeric excess can be determined This method was demonstrated on a combinatorial library of reduction catalyst prepared by combining a set of 22 chiral diamine-based ligands, e.g., I, with four different metal species. As a model reaction, the enantioselective reduction of benzoyl formic acid to (S)-mandelic acid was studied identifying the optimal catalyst as a combination of [RuCl2(p-cym)]2 with the chiral diamine ligand I.
