Dearomatization with Axial‐to‐Central Chirality Conversion
European Journal of Organic Chemistry, EarlyView.Atropisomers are exciting synthetic targets with unique properties, which find applications in many fields of chemistry. However, considering them as substrates is not very frequent, notably in the context of dearomatization reaction. We wish to discuss the different strategies for the dearomatization of aromatic atropisomers with axial‐to‐central ...

European 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.
