Summary: Beta-cyclodextrin covalent organic frameworks (beta-CD COFs) with uniformly distributed chiral recognition sites and good chemical stability have shown great potential in enantioseparation. In this study, two novel functional beta-CD COFs were constructed through post-modification, and they exhibited excellent selectivity and repeatability in chiral separation. The mechanism of chiral recognition and enhanced enantioselectivity of functional beta-CD COFs were further demonstrated.

Summary: This study successfully achieved heterogeneous enantioselective catalysis by modulating the chiral microenvironment around Lewis acid sites in solid-phase catalysts. Chiral metal-organic frameworks (MOFs) were synthesized by anchoring chiral hydroxylated molecules onto Zr-oxo clusters in achiral PCN-222(Cu). The resulting chiral MOFs exhibited regulated enantioselectivity of up to 83% ee in the asymmetric ring-opening of cyclohexene oxide. The chiral molecules created a multilevel microenvironment around the catalytic sites in the MOF, which played crucial roles and synergistically promoted chiral catalysis.

Summary: This study demonstrates the formation of highly interpenetrated frameworks by assembling tetrahedral pyridine ligands and copper dichloride. The presence of very large adamantane-shaped cages in these frameworks makes them new entries in the collection of diamondoid-type metal-organic frameworks (MOFs). The degree of interpenetration in these networks is among the highest reported and increases with the size of the ligand. The voids in these frameworks take up to 63% of the unit cell volume, which is significantly higher than typical frameworks.

Summary: This study describes a gold-catalysed cycloisomerization of 1,5-diynes, providing a selective access to 1,3,4-trisubstituted pyrroles. The cationic gold catalyst activates the ynamide moiety, initiating the cycloisomerization to produce the pyrrole core. Water acts as an external nucleophile to trap the vinyl cationic species, leading to the formation of 1,3,4-trisubstituted pyrroles with high selectivity.

Summary: In this study, hot water and green liquor pretreatments were performed on Eucalyptus wood. The cellulase adsorption behavior on isolated lignins and model compounds was investigated using QCM-D and AFM. The results showed that hot water pretreated lignin adsorbed more cellulase compared to green liquor pretreated lignin and protolignin. The interaction force between lignin and cellulase followed the order of hot water pretreated lignin > green liquor pretreated lignin > protolignin. Additionally, the presence of a ketone group in the monomeric lignin model promoted higher cellulase adsorption compared to the hydroxyl group or aldehyde group.

The shell composition and morphology of the nanostructures can be modified by assembling with different Ti ions and auxiliary ligands. The sensitized titanium outer shell enhances the photocurrent response and the core-shell nanostructures act as stable and efficient catalysts for CO2 cycloaddition with epoxides under ambient conditions.

Summary: Transition metal-catalyzed divergent synthesis through alternation of the catalyst is demonstrated, providing an operationally simple way to access different valuable products from the same reactants. A gold-catalyzed cascade reaction of conjugated diynamides with allylic alcohols is described, giving selectively substituted allenes and furans by varying the catalysts. Mechanistic studies reveal a [3,3]-sigmatropic rearrangement and an intramolecular Himbert arene/allene Diels-Alder cycloaddition as additional reaction sequences to access dearomatized products with bicyclo[2,2,2]octadiene core.

Summary: This study reports 2D lead-MOFs that generate white light through the combined effect of free excitons and self-trapped excitons. The synthesized BIF-142-Cl exhibits outstanding white-light emission with color coordinates close to pure white light, excellent color rendering index, and gentle correlation color temperature. Additionally, the emission can be adjusted from blue to white light by changing the excitation wavelength. This synthetic strategy not only offers potential for solid-state lighting materials but also expands possibilities in anticounterfeiting, display media, and information identification fields.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
