What is Asymmetric Conjugate Addition of Azide to α,β-Unsaturated Carbonyl Compounds Catalyzed by Simple Peptides about?

Stimulated by the efficiency exhibited by enzymes, chemists have sought not only to understand the mechanistic basis for enzymatic reactions, but also to reproduce and even surpass their capabilities. The complementary fields of enzymatic catalysis and transition metal based asymmetric catalysis have recorded many successes in the field of enantioselective reaction development. One question at the interface of these The best fit for c M T versus T in the range of 9 ± 300 K (solid line shown in Figure a) leads to the following parameters: J/k 71.18 K, J'/k 0.58 K, g 2.07 and R 2.0 Â 10 À2 (R S[(c M ) obs À (c M ) calcd ] 2 /S[(c M ) obs ] 2 ). The small positive J' value implies that the exchange interaction through the axial asymmetrical EE bridging azide is very weakly ferromagnetic. This is mainly because of the strict orthogonality of s x and p z azide orbitals. [3b] The low temperature magnetic data (2 ± 20 K) measured at different external fields between 200 Oe to 10 kOe indicate that the value of c M T increases greatly with decreasing magnetic field. This result suggest that the presence of field-saturation effects in addition to the possible weak inter-layer antiferromagne
