Synthesis of Unnatural Amino Acids via β‐Aminoaldehyde C–H Arylation using HAT‐Metallaphotoredox Catalysis

Advanced Synthesis &Catalysis, EarlyView.
Abstract Unnatural amino acids play a crucial role in advancing protein engineering and drug development. In this study, we present the synthesis of a series of γ‐aryl‐keto‐α‐amino acids through the direct C−H arylation of readily accessible β‐aminoaldehydes and aryl bromides, promoted by hydrogen atom transfer combined with metallaphotoredox catalysis.

Biomimetic Orthogonal Removal of Arylacyl Protecting Groups from the C‐Terminus of Substituted Amino Acids and Oligopeptides via Flavin N(5)‐iminium Covalent Adducts

Advanced Synthesis &Catalysis, EarlyView.
Abstract Flavin co‐factors and other flavin derivatives are traditionally associated with one‐ or two‐electron redox reactions. Flavins also form covalent intermediates with a variety of substrates. While extensive attention has focused on reactions at the C(4a) position of the flavin ring, recent interest has shifted toward the dynamic potential of ...

Double‐Sided Control of Product Type Preference in the Visible‐Light Initiated Reaction of 1,3‐Dicarbonyl Compounds with Alkenes

Advanced Synthesis &Catalysis, EarlyView.
Abstract The demonstrated light‐initiated addition of radicals formed on an active methylene group to styrene derivatives exhibits a product selectivity influenced by the presence of a protic solvent. Under protic conditions, the predominant products are branched compounds with the alkene moiety attached to the methylene group.
