Alkynyltriazenes in Photochemical Metal‐Free Doyle–Kirmse Rearrangements

open access: yesAngewandte Chemie International Edition, EarlyView.
A metal‐ and additive‐free photocatalytic Doyle–Kirmse reaction of alkynyl triazenes is described, proceeding via cyanocarbene intermediates. This strategy enables the efficient construction of highly substituted asymmetric carbon centers with broad substrate scope, delivering synthetically valuable nitriles.

High Yield Branched Puromycin Linker Design Enables Efficient cDNA Display and Chemical Modification of Peptides

open access: yesBiotechnology and Bioengineering, EarlyView.
A novel puromycin linker for cDNA display was synthesized via SPAAC reaction. Its functionality was confirmed by recovering intact DNA after selection against EpCAM. The system also enabled the verification of bicyclic peptides during display, demonstrating its utility for constructing and screening structurally complex peptide libraries.

Synthesis of Oligo‐Sulfonimidates by Exponential Growth via Sulfur‐Phenolate Exchange Reactions

open access: yesChemistryEurope, EarlyView.
A highly flexible iterative exponential growth strategy is used in combination with the sulfur‐phenolate exchange reaction to develop sequence‐defined oligosulfonimidates (16 mer). Combining this with sulfur‐fluorine exchange‐based iterative step growth, a bespoke 20 mer (Mw = 8.5 kDa) can be synthesized.
