Operating a Multi-Level Molecular Dimer Switch through Precise Tip-Molecule Control [PDF]

open access: yesarXiv
Controlling structural transitions between molecular configurations is crucial for advancing functional molecular electronics. While reversible switching of bistable two-state molecules has been achieved, creating molecular systems that can be controllably switched between multiple configurations often requires complex synthetic methods, presenting a ...

Development of an Organoautocatalyzed Double σ‐Bond C(sp2)‐N Transamination Metathesis Reaction

open access: yesAngewandte Chemie International Edition, Accepted Article.
The transamination reaction, which involves the conversion of one amine to another, traditionally relies on biological enzyme catalysts. Although chemists have recently developed a few transition metal‐catalyzed methods, mimicking these enzymes to interconvert amine groups in acyclic substrates via transamination metathesis of a single C(sp2)–N bond ...

Streamlining SuFEx Inhibitor Development: A Unified Approach Using Photolabile and Orthogonal Sulfinate Protecting Groups

open access: yesAngewandte Chemie International Edition, Accepted Article.
Sulfonyl fluorides have gained significant importance due to their classification as a click reaction and therefore have seen increased use in drug discovery and biochemistry. Their use, however, is complicated by the methods by which they are synthesized and their general synthetic instability.

Advances in Metal‐Free Transamidation: A Sustainable Approach to Amide Bond Formation

open access: yesChemistry – An Asian Journal, EarlyView.
This review highlights the recent developments of transamidation reactions under metal‐free reaction conditions. Various amines including weak nucleophilic amines such as aromatic amines have been used to achieve the transamidation reactions under mild and relatively green reaction conditions. Abstract The amide functionalities are a crucial functional
