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 ...

Photoinduced Catalytic Alkylation of Active Methine Compounds with Nonactivated Alkenes Using Yttrium Triflate as a Lewis Acid Catalyst

Advanced Synthesis &Catalysis, EarlyView.
Abstract Photoinduced catalytic alkylation reactions of active methine compounds with nonactivated alkenes have been developed using an organophotocatalyst, a metal Lewis acid, an arylthiol, and an amine base catalyst system. The alkylation reactions proceeded smoothly under ambient conditions with blue light irradiation, affording the desired products

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.
