Peptide‐Carbazolyl Cyanobenzene Conjugates: Enabling Biomolecule Functionalization via Photoredox and Energy Transfer Catalysis

open access: yesAngewandte Chemie, EarlyView.
We introduce two methods for incorporating carbazolyl cyanobenzenes onto peptides: a C‐terminus decarboxylative functionalization and a Cys‐selective SNAr reaction. Both conjugates exhibit excellent photoredox/energy‐transfer properties, enabling their use for C‐terminal alkynylation and Cys‐selective thiol‐ene reactions on peptides, as well as ...

Enantiopure Chiral Crystals: A Powerful Tool for Absolute Asymmetric Synthesis

open access: yesAsian Journal of Organic Chemistry, EarlyView.
This review covers absolute asymmetric syntheses, which allow the preparation of enantiomerically enriched chiral compounds from achiral precursors. By exploiting the crystallization of certain compounds as a conglomerate, enantiopure chiral crystals are spontaneously obtained.

Self‐Assembly of a Customizable Library of Nickel Trifluoromethylation Catalysts via Selective C─F and C─O Bond Cleavage

open access: yesAngewandte Chemie, EarlyView.
Carbatranes and anionic pincer ligands were self‐assembled via one‐pot C─F or C─O bond cleavage and the formation of C─O, C─N, or C─C bonds, forming ligand architectures inaccessible by common synthetic methods. This approach allowed to build a customizable library of nickel catalysts for light‐induced C─H bond trifluoromethylation.

Plantacare 2000: A Biosurfactant for an Eco‐Friendly Palladium Catalyzed Cyanation of Aromatic Bromides

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Abstract We introduce here Plantacare 2000 (PL‐2000), a renewable biosurfactant for sustainable palladium‐catalysed cyanation reactions in water. PL‐2000 is derived from plant‐based raw materials, is fully biodegradable, nontoxic to the aquatic environment and commercially available without the need for complex synthesis.

Direct Activation of Sulfides by C–H Oxidation with Photoexcited Nitroarenes: Formal Manipulations of the C─S Bond

open access: yesAngewandte Chemie, EarlyView.
Photochemical anaerobic oxidation of sulfides, using nitroarenes as bifunctional reagents, enables the formal manipulation of the C─S bond. The method allows direct and selective access to versatile carbonyl compounds from largely inert sulfides by C–H oxidation, thus avoiding multistep activation by sulfur oxidation.
