Abstract:
The Cover Feature shows collaborative work from the O'Donoghue and Smith groups that describes mechanistic studies of the popular NHC-catalyzed intramolecular Stetter reaction process. A word-cloud approach was used to create a visual representation of the manuscript through using and scaling the most popular and relevant words from the publication, superimposed on the chemical catalytic cycle, conveying crucial information at a glance in a visual manner. More information can be found in the Communication by A. Smith et al.

Abstract:
The cycloaddition of azomethine ylides to [60]fullerene (C 60 ) has been studied in ortho-dichlorobenzene ( o -DCB) by evaluating the impact of an ionic liquid (IL) additive. The solvent effect has been addressed by evaluating the activation parameters of the cycloaddition and the boosting effect of the MW induced dielectric heating. The IL additive plays a twofold role of stabilizing the dipolar ylide intermediate and favoring the retro-cycloaddition at high temperature regime. Under the conditions explored, a combined kinetic and thermodynamic preference favors the selective formation of trans bis-fulleropyrrolidine regioisomers, in agreement with the DFT computational analysis.

Abstract:
Allosteric regulation, i.e. the control exerted on an orthosteric site by an effector interacting at a distinct and distant site, represents a prime example of a precise tuning system of several key biological processes like gene transcription, cell adhesion and, most importantly, signal transduction. Since its discovery sixty years ago, the molecular mechanisms underlying this phenomenon have been extensively investigated. The aim of this minireview is to introduce the reader to the topic of protein allostery. In particular, we briefly overview the allosteric models postulated over the years and we describe the most relevant chemical and biophysical approaches reported so far for the identification of putative allosteric sites and/or for the investigation of allosteric signal propagation throughout the protein. An outlook of the main computational and experimental methods is followed by four case studies representative of different proteins classes: enzymes, hub proteins, cell receptors and intrinsically disordered proteins.

Abstract:
The trick is a switch. The Staudinger synthesis of β-lactams has never been performed as a three-component reaction, mixing amines, carbonyl derivatives and ketene precursors. Recent advances in the visible light mediated Wolff rearrangement of diazoketones allowed us to perform, for the first time, a 3-component Staudinger reaction, by mixing the reagents in the dark and switching the light on after imine formation. The new photoinduced reaction parallels the classic methods in terms of efficiency and selectivity, and adds to the existing multicomponent approaches for the preparation of combinatorial libraries of compounds. A thorough optimization of the reaction conditions was performed both for the classic two component reaction and for the novel three component version of the photoinduced Staudinger reaction.

Abstract:
The Front Cover shows specific cell staining with a bright fluorescent label. The label is composed of two functional units: a protein-based binder that selectively binds to the target molecules in the cell and an emitter unit containing multiple individual fluorophores providing high brightness of the label. More information on recent advances of fluorophore multimerization for generation of bright fluorescent labels for flow cytometry and fluorescence microscopy applications can be found in the Minireview by D. Yushchenko et al.

European Journal of Organic Chemistry; doi:10.1002/ejoc.202100601

Abstract:
The Front Cover shows electron transfer from a photoexcited fullerene to a strong electron acceptor. By connecting the xanthylium moiety to the typical electron acceptor, fullerene, the electron transfer was achieved with fullerene as the electron donor, contrary to the usual case. The formed fullerene radical cation was confirmed by transient absorption spectra. More information can be found in the Communication by H. Yamada, N. Aratani et al.

Abstract:
The Front Cover shows the methodology for the synthesis of diversified “Y-enyene” BODIPY derivatives, obtained through the Pd-catalyzed Sonogashira coupling reaction of gem-dibromo BODIPY and alkyne derivatives. The coupling products possess interesting spectral properties (UV/Vis and fluorescence), providing the potential to develop fluorescence probes and photosensitizers for photodynamic therapy (PDT). Protonation of dimethylaminphenyl substituted BODIPYs induces changes in their spectral properties, from fluorescence off-to-on. Their strong electrochromic properties render these derivatives most suitable for the construction of multifunctional electro- and photo-chemical molecular switches. More information can be found in the Full Paper by J. E. van Lier et al.

Abstract:
The Cover Feature shows a combination that could be called the ugly duckling of the Ugi 4-component reactions, which involves the concomitant use of the ammonia/formaldehyde pair. There was not a single methodology so far to successfully achieve this goal. The metamorphosis could finally happen with the intermediacy of hexamethylenetetramine (HMTA), which allows the in situ generation of both ammonia and formaldehyde for the Ugi reactions with carboxylic acids and isocyanides, yielding a variety of acylaminoacetamide derivatives in good to excellent yields.

Abstract:
The Front Cover shows Mont Aiguille, located in the Vercors massif, France. The limestone cliffs of Mont Aiguille are very popular with climbers. Its first climb in 1492 would have marked the birth of mountaineering. From a chemist′s point of view, the sea of fog can hide a complex landscape as in the case of asymmetric catalysis where linearity between product ee and ligand ee cannot allow to conclude on the exact mechanism.

Abstract:
The cycloaddition of CO2 to N-alkyl aziridines was efficiently promoted by the convenient TPPH2/TBACl binary catalytic system. The metal-free procedure was effective for the synthesis of differently substituted N-alkyl oxazolidin-2-ones in yields up to 100 % and excellent regioselectivities (up to 99 %). The mechanism of the reaction was proposed based on a DFT study which indicated the formation of an adduct between TPPH2 and TBACl as the effective catalytic active species.

Abstract:
The Front Cover shows the one-pot procedure for the introduction of aminoalkyl chain through dialkyl carbonate chemistry into different phenolic substrates. This green approach is a direct alcohol substitution that avoids the use of chlorine chemistry giving CO2 and ethanol as the only reaction by-products. The proposed procedure has numerous potential applications as N,N-dialkyl ethylamine moieties are incorporated in many pharmacophore scaffolds such as Tamoxifen, Raloxifene, Amiodarone, Phenyltoloxamine and Trifenagrel. The authors thank Thomas Bassano for creating the artwork. More information can be found in the Communication by F. Aricò et al.
