Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

Emerging Trends in Organic Photoreactions Utilizing Disulfides

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Disulfides are versatile, nontoxic alternatives to metal photocatalysts. This review explores their role as photoactivated thiyl‐radical precursors and bifunctional catalysts (HAT/electron shuttling) in diverse transformations. Strategies for electronic tuning and development into recyclable heterogeneous materials are highlighted for sustainable ...

Design and Synthesis of Lactose‐Derived Ligands and Their Application in Asymmetric Friedel–Crafts Alkylation

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This work describes the synthesis of lactose‐ and glucose‐derived chiral ligands and their application in the catalytic enantioselective Friedel–Crafts alkylation of indole with a series of trans‐β‐nitrostyrenes. The optimal ligand was an acetate protected, lactose‐derived pyridyl imine and its zinc complex afforded ees up to 93% and yields up to 93 ...

Hofmann Degradation of Asparagine and Glutamine as an Efficient Approach for the Synthesis of Derivatized Lysine Homologs

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A practical and scalable route to C1 and C2 lysine homologs has been developed using Hofmann degradation of N‐protected L‐asparagine and L‐glutamine as the key step. These short‐tether scaffolds enable efficient synthesis of diverse Fmoc‐protected noncanonical amino acids (ncAAs) bearing donor, acceptor, redox‐active, and fluorescent residues.
