Repurposing the Pummerer Rearrangement: Determination of Methionine Sulfoxides in Peptides. [PDF]
Chembiochem, 2020 AbstractThe reversible oxidation of methionine residues in proteins has emerged as a biologically important post‐translational modification. However, detection and quantitation of methionine sulfoxide in proteins is difficult. Our aim is to develop a method for specifically derivatizing methionine sulfoxide residues.

Rapid Assembly of Tetrasubstituted Furans via Pummerer-Type Rearrangement. [PDF]
J Am Chem Soc, 2021 Despite the many methods available for the synthesis of furans, few methods remain that allow for the custom-made assembly of fully substituted furans. Here we report a powerful protocol to rapidly construct tetrasubstituted, orthogonally functionalized furans under mild reaction conditions. The developed method involves the regioselective ring-opening

The Sulfinate-Sulfone Pummerer Rearrangement [PDF]
Phosphorus, Sulfur, and Silicon and the Related Elements, 1994 Abstract α-CH acidic sulfoxides with additional electron-withdrawing substitution at C-α afford generation of α sulfonyl thioethers during reaction with sulfinyl chlorides. Some reaction details as well as a mechanistic proposal are presented.

Metal-Free Arylation of Benzothiophenes at C4 by Activation as their Benzothiophene S-Oxides. [PDF]
Angew Chem Int Ed Engl, 2023 Benzothiophenes are key structures in materials and medicines and methods for their selective C−H functionalization are highly prized. Activation of benzothiophenes bearing electron‐withdrawing groups at C3 as their S‐oxides enables formal C−H/C−H coupling with phenols to access C4 arylated benzothiophenes.

α-Functionalisation of Cyclic Sulfides Enabled by Lithiation Trapping. [PDF]
Angew Chem Int Ed EnglLithiation and trapping at convenient temperatures (0/−10 °C) of five cyclic sulfides such as tetrahydrothiophene, tetrahydrothiopyrans and a thiomorpholine enables straightforward α‐functionalisation. Trapping with a wide range of electrophiles generates more than 50 diverse α‐substituted saturated sulfur heterocycles that are not easily synthesised ...
