We report herein a highly efficient stereodivergent reaction on racemic quinolinyl-substituted tertiary alcohols via Ir-catalyzed asymmetric transfer hydrogenation, which affords structurally unique chiral 1,2,3,4-tetrahydroquinolines bearing both endo- and exocyclic chirality. Upon mediation of the configuration of the catalyst, all four diastereomers can be achieved with excellent ee and dr (generally >95% ee). Through reoxidation, the products can be converted into enantiopure starting materials, thus realizing a formal resolution of challenging tertiary alcohols.

An efficient Ir-catalyzed enantioselective intramolecular allylic substitution reaction for the synthesis of five- and six-membered N,O-heterocycle compounds has been achieved. This method offers a facile, straightforward access to a diverse range of 1,3,4-oxadiazines with good yields (up to 88%) and excellent enantioselectivities (up to 95% ee), while oxazolines and 1,3-oxazines have also been afforded with comparable yields and ee values.

Herein, a family of cyclic electron donor-acceptor structures was synthesized and characterized, in which carbazole was used as the donor integrated into dehydrobenzoannulene (DBA). Subsequent solvent-dependent fluorescence spectra revealed that all resultant azaDBAs exhibited pronounced intramolecular charge transfer properties. Benefiting from this unique electron-delocalized architecture, all resulting azaDBAs demonstrated strong and stable electrochemiluminescence emission in the visible region. Finally, an azaDBAc-based epinephrine sensor was developed, enabling ultrasensitive detection for both the early diagnosis of neurodegenerative diseases and dynamical monitoring of neurotransmitters.

A ligand-controlled switchable nickel-catalyzed coupling reaction between nitriles and aryl triflates has been developed, enabling the divergent synthesis of two privileged classes of molecules—ketones and diarylmethanes—from identical starting materials. The chemoselectivity is mainly dictated by the choice of phosphine ligand: employing dppp as the ligand promotes reductive addition/hydrolysis, yielding ketones, while switching to Xantphos directs the pathway toward decya-native cross-coupling to furnish diarylmethanes. This protocol features broad substrate scope (up to 60 examples), excellent functional group tolerance, and high chemoselectivity, thus providing a versatile and stepeconomical strategy for modular synthesis of ketones and diarylmethanes from readily available nitriles.

The emergence of green chemistry principles has driven researchers to develop more sustainable methods for organic synthesis. However, despite this emphasis on environmentally friendly transformations, the green chemistry metrics are often overlooked when assessing the true environmental impact of a reaction, making it difficult to objectively compare new methods with traditional approaches or to determine their true sustainability. With this in mind, this work presents an approach for synthesizing chalcogenylbenzo[b]furans through the visible light-driven generation of electrophilic chalcogen species and further evaluate the sustainability of the developed protocol using various traditional and emerging green chemistry metrics to effectively assess reagent utilization, waste generation and toxicity, and material recovery. The synthetic methodology utilizes the combination of diaryldichalcogenides and carbon tetrabromide to promote the oxidative cyclization of 2-alkynylanisoles, leading to the formation of both selenylbenzo[b]furans and thiobenzo[b]furans in satisfactory yields. The study demonstrates the effectiveness and versatility of the method by employing a range of substrates. Furthermore, the obtained chalcogenylbenzo[b]furans were subjected to an in silico screening to evaluate their antioxidant potential through molecular docking, assessing their interaction with xanthine oxidase and NADPH oxidase enzymes, as well as predicting their ADME/T profiles.

Herein, an unprecedented Rh(III)-catalyzed C6-arylation of N-pyridyl-2-pyridones with diazonaphthalen-2(1H)-ones along with directing group migration leading to the formation of 6-(2-(pyridin-2-yloxy)naphthalen-1-yl)pyridin-2(1H)-ones is reported. The reaction goes through a cascade process including C–H bond metalation, carbene formation, migratory insertion, and nucleophilic attack of the hydroxyl group of the in situ introduced naphthol moiety onto the pyridyl unit, followed by pyridyl migration. Importantly, this method has been effectively applied to the synthesis of several drug analogues, such as gemfibrozil, ibuprofen, and menthol. Moreover, it exhibits excellent atom- and step-economy, along with remarkable compatibility of functional groups, and high efficiency.

The Securinega alkaloids are a diverse family of polycyclic alkaloids with broad biological importance. In this study, a formal [4+2] cycloaddition strategy has been used to complete the biomimetic total synthesis of six Securinega alkaloids, notably using biosynthetically plausible scaffold-forming steps and aqueous reaction conditions. A further four alkaloids were also generated via subsequent rearrangement reactions. Altogether, the total syntheses of ten Securinega alkaloids are described, in one or two linear steps from proposed biosynthetic precursor menisdaurilide. These results support the hypothesis that the same or similar pathways may operate in planta.

The example of carbonyls as alkenyl carbanions for deoxygenative cross-coupling with alkyl electrophiles has been developed, facilitating the efficient synthesis of alkenes and enabling carbonyl 1,2-transposition alkylation. This protocol features a one-pot three-step synthesis, compatibility with diverse functional groups, mild reaction conditions, and latestage functionalization of biomolecules. Initial experiments and DFT mechanistic studies suggest that the in-situ generated alkenyl boronic esters play a crucial role as intermediates in this reaction, and this transformation involves C-O bond borylation and the Suzuki coupling reaction under transition metal-free conditions.

This DFT computational study establishes distinct mechanistic pathways for the Rh(I)-catalyzed carbometalation of dihydropyridines and dihydroquinolines, underpinning their divergent enantioselectivity. For dihydropyridines, the energetically preferred route—comprising alkene insertion, protodemetalation, and transmetalation to yield the S-configured product—is stabilized by a chair-like pyridine ring, as evidenced by NPA charge. The enantioselectivity, controlled at the protodemetalation step, arises from differential distortion energies in the competing transition states. Conversely, dihydroquinolines undergo a modified pathway that includes oxidative addition, bypassing direct protodemetalation due to a destabilizing twist-boat conformation. Here, enantiocontrol is shifted to the reductive elimination step, governed by disparities in key dihedral angles among the transition states.
