On July 2, 2021, Kabes, Connor; Lucas, Reagan; Gunn, Jack; Gladysz, John published an article.Computed Properties of 10472-24-9 The title of the article was Chiral Cobalt(III) Tris(1,2-diamine) Catalysts That Incorporate Nitrogenous Base Containing Anions for the Bifunctional Activation of Nucleophiles and Electrophiles in Enantioselective Addition Reactions. And the article contained the following:
Here, The lipophilic diastereomeric cobalt complexes Λ or Δ-[Co((S,S)-dpen)3]3+ 2Cl-BArf- (Λ or Δ-(S,S)-23+ 2Cl-BArf-; dpen/BArf- = 1,2-diphenylethylenediamine/B(3,5-C6H3(CF3)2)4-) ,salts of nicotinates, isonicotinates, related sulfonates, and N,N-dimethylaminobenzoate were applied addition reactions. The 6-chloronicotinate salt gaves slower rates and lower ee values, and the 6-aminonicotinate salt gave faster rates and higher ee values. The 6-Me, 2-methoxy, and unsubstituted analogs afforded intermediate results. The 6-aminonicotinate catalyst was applied to additions of di-Me malonate to aryl-substituted nitroolefins and additions of 1,3-dicarbonyl compounds to di-t-Bu azodicarboxylate, with average yields/ee values of 90%/85% and 94%/77%, resp. The authors were unaware of other ionic catalysts for which Bronsted bases was productively incorporated into the anions, which were seldom if ever purposefully functionalized in any manner. The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).Computed Properties of 10472-24-9
