Enhanced cooperative activation effect in the hydrolytic kinetic resolution of epoxides on [co(salen)] catalysts confined in nanocages

(Chemical Equation Presented) Being cagey: More than two chiral [Co-(salen)] catalyst molecules can be confined in one nanocage of SBA-16 by reducing the pore entrance size by silylation. The [Co(salen)]/SBA-16 catalysts with more than two [Co(salen)] complexes in each cage show a significantly enhanced cooperative activation effect and exhibit much higher activity than the homogeneous [Co(salen)] catalyst in the hydrolytic kinetic resolution of epoxides (see scheme).

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 4254-15-3! Reference of 4254-15-3

Concise synthesis of stagonolide-F by ring closing metathesis approach and its biological evaluation

The first total synthesis of 9-membered macrolide, stagonolide-F (3), starting from commercially available 1,5-pentane diol is reported. A combination of Jacobsen’s hydrolytic kinetic resolution (HKR) and Sharpless epoxidation is used for the creation of two stereogenic centers, while ring-closing metathesis (RCM) strategy was used for the construction of the lactone ring. The molecule synthesized exhibited potent antifungal, antibacterial and cytotoxic activities against all the tested strains.

Relative and absolute stereochemistry of secondary/secondary diols: Low-temperature 1H NMR of their bis-MPA esters

Comparison of the room- and low-temperature 1H NMR spectra of the bis-(R)- or bis-(S)-MPA ester derivative of an open chain sec,sec-1,2-diol allows the easy determination of its relative stereochemistry and in some cases absolute configuration. If the diol is anti, its absolute configuration can be directly deduced from the signs of DeltadeltaT1T2 for substituents R1/R2, but if the relative stereochemistry of the diol is syn, the assignment of its absolute configuration requires the preparation of two derivatives (both the bis-(R)- and bis-(S)-MPA esters), comparison of their room-temperature 1H NMR spectra, and calculation of the DeltadeltaRS-signs for the methines Halpha(R 1) and Halpha(R2) and R1/R2 protons. The reliability of these correlations is validated with 17 diols of known absolute configuration used as model compounds.

Determining the absolute stereochemistry of secondary/secondary diols by 1H NMR: Basis and applications

The absolute configuration of 1,2-, 1,3-, 1,4-, and 1,5-diols formed by two secondary (chiral) hydroxy groups can be deduced by comparison of the NMR spectra of the corresponding bis-(R)- and bis-(S)-MPA esters. The correlation between the NMR spectra of the bis-ester derivatives and the absolute stereochemistry of the diol involves the comparison of the chemical shifts of the signals for substituents R1/R2 and for the hydrogens attached to the two chiral centers [Halpha(R1) and Halpha(R2)] in the bis-(R)- and the bis-(S)-ester and is expressed as Deltadelta.RS Theoretical calculations [energy minimization by semiempirical (AM1), ab initio (HF), DFT (B3LYP), and Onsager methods, and aromatic shielding effect calculations] and experimental data (NMR and CD spectroscopy) indicate that in these bis-MPA esters, the experimental DeltadeltaRS values are the result of the contribution of the shielding/deshielding effects produced by the two MPA units that combine according to the actual stereochemistry of the diol. The reliability of these correlations is demonstrated with a wide range of diols of known absolute configuration derivatized with MPA and 9-AMA as auxiliary reagents. A simple graphical model that allows the simultaneous assignment of the two asymmetric carbons of a 1,n-diol by comparison of the NMR spectra (Deltadelta RS signs) of its bis-(R)- and bis-(S)-AMAA ester derivatives is presented.

The bakers’ yeast reductions of alpha- and beta-keto ester derivatives in the presence of a sulfur compound

Improvement of the enantioselectivity and enhancement of the reactivity were achieved in the bakers’ yeast reduction of the alpha- and beta-keto ester derivatives by the addition of a sulfur compound. High enantioselectivity in the bakers’ yeast reduction of keto esters was accomplished by using combination of an addition of a sulfur compound with an appropriate selection of the alcohol part of the ester.
