Development and Scale-Up of a New Sulfone-Based Bismacycle as a Universal Precursor for Bi(V)-Mediated Electrophilic Arylation (2024)
Journal Article

The scope and practical utility of bismuth(V)-mediated electrophilic arylation have been greatly improved by the recent development of user-friendly protocols based on modular bismacycle reagents. Here, we report the scalable synthesis of a new bench...

Synthesis of Highly Functionalized Bismacycles via Post-Transmetallation Modification of Aryboronic Acids (2023)
Journal Article

Bismacycles featuring a sulfone-bridged scaffold have recently been developed as versatile and convenient electrophilic arylating agents. Here, we report that the exocyclic aryl group, which is ultimately transferred to a nucleophilic coupling partne...

Photochemically Mediated Ring Expansion of Indoles and Pyrroles with Chlorodiazirines: Synthetic Methodology and Thermal Hazard Assessment (2023)
Journal Article

We demonstrate that arylchlorodiazirines serve as photo-activated halocarbene precursors for the selective one-carbon ring expansion of N-substituted pyrroles and indoles to the corresponding pyridinium and quinolinium salts. Preliminary investigatio... Read More about Photochemically Mediated Ring Expansion of Indoles and Pyrroles with Chlorodiazirines: Synthetic Methodology and Thermal Hazard Assessment.

Coaxial Dielectic Spectroscopy as an In-Line Process Analytical Technique for Reaction Monitoring (2023)
Journal Article

Coaxial Dielectric Spectroscopy as an In-Line Process Analytical Technique for Reaction Monitoring (2023)
Journal Article

The suitability of broadband dielectric spectroscopy (DS) as a tool for in-line (in situ) reaction monitoring is demonstrated. Using the esterification of 4-nitrophenol as a test-case, we show that multivariate analysis of time-resolved DS data – col...

Skeletal Editing: Interconversion of Arenes and Heteroarenes (2023)
Journal Article

Skeletal editing involves making specific point-changes to the core of a molecule through the selective insertion, deletion or exchange of atoms. It thus represents a potentially powerful strategy for the step-economic modification of complex substra... Read More about Skeletal Editing: Interconversion of Arenes and Heteroarenes.

meta-Selective C–H arylation of phenols via regiodiversion of electrophilic aromatic substitution (2022)
Journal Article

Electrophilic aromatic substitution is among the most widely used mechanistic manifolds in organic chemistry. Access to certain substitution patterns is, however, precluded by intrinsic and immutable substituent effects that ultimately restrict the d...

Umpolung Synthesis of Pyridyl Ethers by Bi(V)‐Mediated O‑Arylation of Pyridones (2022)
Journal Article

We report that O-selective arylation of 2- and 4-pyridones with arylboronic acids is affected by a modular, bismacycle-based system. The utility of this umpolung approach to pyridyl ethers, which is complementary to conventional methods based on S N...

Modular Synthesis of α,α-Diaryl α-Amino Esters via Bi(V)-Mediated Arylation/SN2-Displacement of Kukhtin–Ramirez Intermediates (2022)
Journal Article

We report a concise and modular approach to α,α-diaryl α-amino esters from readily available α-keto esters. This mild, one-pot protocol proceeds via ketone umpolung, with in situ formation of a Kukhtin-Ramirez intermediate preceding sequential electr...
