Chem. Comm. [CLAC]

Abstract: The association of hydrophobic cavities with porphyrin derivatives has been used to mimic hemoprotein structures. The most employed cavity in this field is the β-cyclodextrin (β-CD) and scaffolds combining β-CDs and porphyrins are expected to inspire the combination of porphyrins and cucurbiturils in a near future. Aside from providing water solubility to various porphyrinic...[more]

EurJOC [SOCAT]

Abstract: Three new cis‐diquinoxaline spanned cavitands were successfully synthesized. These cis‐diphosphinated derivatives were applied in homogeneous gold‐catalyzed dimerization and hydration of alkynes as well as rhodium‐catalyzed styrene hydroformylation. The results were ranked with those obtained with their trans‐diphosphinated isomeric analogues. The structure‐activity relationship...[more]

EurJIC [SOCAT]

Abstract: A unique, covalently constructed capsular catalyst obtained by reaction of [Ni(η5‐C5H5)(1,5‐cyclooctadiene)] BF4 with the double‐calixarene‐derived diphosphine 1,3‐bis(5‐diphenylphosphino‐25,26,27,28‐tetrapropoxycalix[4]aren‐17‐yl)benzene (1) has been shown to polymerise butadiene at a rate considerably superior to that of previously known catalysts. The reported results indicate that...[more]

ChemRxiv [OMECA]

Abstract: Metalloenzymes use earth-­abundant non-­noble metals to perform high‐fidelity transformations in the biological world. To ensure chemical efficiency, metalloenzymes have acquired evolutionary reactivity­‐enhancing tools. Among these, the entatic state model states that a strong steric entatic state, strongly improving the reactivity. However, while the original definition refers both...[more]

ChemCatChem [OMECA]

Abstract: Metalloenzymes are nature's own catalysts and offer as such endless inspirational source for the chemists seeking selectivity in transformations. Metalloenzymes involved in oxidoreduction processes have specific subunits dedicated to electron and proton transfer, and these so‐called redox cofactors perform highly orchestrated redox events. This minireview offers a perspective on the...[more]

Plant Cell [SOPhy/RMN]

Abstract Flowers are essential but vulnerable plant organs, exposed to pollinators and florivores, yet surprisingly, flower chemical defenses were rarely investigated. We show here that two clustered terpene synthase and cytochrome P450 encoding genes (TPS11 and CYP706A3) on chromosome 5 of Arabidopsis thaliana are tightly co-expressed in floral tissues, upon anthesis and during floral bud...[more]
