FLP Mediated Conversion of Difluorobenzylalkynes to Fluoroallenyl Oniums via an SN1’ Pathway

open access: yesChemistry – A European Journal, EarlyView.
Frustrated Lewis pair (FLP) selective C‒F activation of difluorobenzylalkynes allows the formation of fluoroallenic oniums via an SN1’ substitution pathway. The fluoroallenic onium salts are synthetic precursors that allow subsequent functionalization at allenic and onium positions.

1,2‐Bis(boronate) Arenes by Borylation Directed Borylation

open access: yesAngewandte Chemie, Volume 138, Issue 44, 26 October 2026.
Boron electrophiles derived from tetrabromo‐pyrazaboles and AlCl3 affect the regioselective vicinal double C–H borylation of a range of arenes and polycyclic aromatic hydrocarbons (PAHs). A subsequent pinacol installation step then affords the vicinal bis‐boronate ester‐substituted arene/PAH.

Trends and Future Directions in Organic Chemistry for Drug Discovery

open access: yesChemistry – A European Journal, EarlyView.
Organic synthesis is being reshaped by the convergence of catalytic innovation, automation, artificial intelligence, and emerging therapeutic modalities. Late‐stage functionalization, photoredox and electrochemical methods, biocatalysis, flow chemistry, DELs, and proximity‐based drugs are examined as components of closed‐loop discovery.

Alkali Metal Mediated Redox Tuning in Bis(μ‐OH) Dinickel(II) Complexes

open access: yesChemistry – A European Journal, EarlyView.
Alkali metal ions are ubiquitous in both enzymatic and synthetic catalytic media. The present study highlights the powerful influence common monocations have on the structural and electrochemical properties of catalytically relevant bis(μ‐hydroxo) dinickel diamond cores, through a well‐defined series of heterometallic clusters (Li+, Na+, K+, and Cs ...

Enantioconvergent construction of stereogenic silicon via Lewis base-catalyzed dynamic kinetic silyletherification of racemic chlorosilanes

open access: yesNature Communications, 2023
Organosilanes possessing an enantioenriched stereogenic silicon center are important in many branches of chemistry, yet they remain challenging to synthesize in a practical and scalable way. Here we report a dynamic kinetic silyletherification process of

Multienzyme Cascade Reactions: Compatibility, Cooperativity, and Control

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 21, 3 November 2026.
Multienzyme cascade reactions are sequences of telescoped biotransformations that avoid the isolation of intermediates and offer significant efficiency advantages over traditional multistep routes. This review article highlights recent examples of multienzyme cascades and explores how their success depends on the consideration of compatibility ...

Enantioselective synthesis of β-aryl-γ-lactam derivatives via Heck–Matsuda desymmetrization of N-protected 2,5-dihydro-1H-pyrroles

open access: yesBeilstein Journal of Organic Chemistry
We report herein an enantioselective palladium-catalyzed Heck–Matsuda reaction for the desymmetrization of N-protected 2,5-dihydro-1H-pyrroles with aryldiazonium salts, using the chiral N,N-ligand (S)-PyraBox.

Linker Symmetry Lowering as a Strategy to Tune Electronic Properties in Two‐Dimensional Conductive MOFs

open access: yesChemistry – A European Journal, Volume 32, Issue 40, 27 October 2026.
We present a two‐dimensional conductive metal‐organic framework (2D cMOF) constructed from an organic linker with lower symmetry than those commonly used in related systems. The resulting reduction in lattice symmetry lifts band degeneracies, reshapes the electronic structure, and opens a larger band gap.

Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 40, 27 October 2026.
Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]

Direct Access to Chiral Piperidines by Enantioselective HAT‐Initiated C(sp3)─H Oxidation

open access: yesAngewandte Chemie, Volume 138, Issue 44, 26 October 2026.
The direct desymmetrization of piperidines is achieved through manganese‐catalyzed enantioselective α‐C(sp3)─H oxidation with hydrogen peroxide, affording versatile chiral N,O‐acetals in good yields and with high enantio‐ and diastereoselectivity. These intermediates provide access to diverse functionalized piperidines with retention of chirality ...
