Tunable Preparation of β‐Substituted Alkenoate Esters via Radical Alkenylation of C(sp3)–H Bonds with Allenoates

Advanced Synthesis &Catalysis, EarlyView.
Abstract A photocatalytic strategy for the radical alkenylation of aliphatic C(sp3)–H bonds with 2,3‐allenoate esters is described. The protocol takes place upon irradiation of the reaction mixture in the presence of the decatungstate anion, which triggers C−H cleavage in the chosen aliphatic substrates.

Effective and Practical Stereoselective Synthesis of Nutlins Precursors by Immobilization of Privileged Chiral Mono‐Amidine Catalyst

Advanced Synthesis &Catalysis, EarlyView.
Abstract A strategy for the immobilization of Johnston's Mono(AMidine) catalyst (MAM) onto polystyrene, silica and hybrid silica‐polystyrene nanoparticles is presented. The catalyst activity was evaluated in the stereoselective aza‐Henry reaction leading to the pivotal β‐amino nitroalkane precursors of the anti‐cancer agents Nutlins (with Nutlin‐3a as ...

Constant enzymatic in situ production of H₂O₂ for an Unspecific Peroxygenase by an L‐amino acid oxidase

Advanced Synthesis &Catalysis, Accepted Article.
Unspecific Peroxygenases have been the subject of a lot of research in the recent past as they offer opportunities for green hydroxylation reactions using hydrogen peroxide (H₂O₂) as donor. A striking problem of UPOs is their low stability against their own co‐substrate H₂O₂.

Development of Photo‐Biocatalytic Redox System for Asymmetric Synthesis of Optically Active Amines Using Blue Light and Transaminases. A Case Study Toward Mavacamten

Advanced Synthesis &Catalysis, EarlyView.
Abstract α‐Chiral amines are versatile building blocks for the asymmetric synthesis of optically pure high‐added‐value chemicals, including pharmaceuticals, agrochemicals, and natural products. Herein, we report a one‐pot, two‐step sequential deracemization of racemic sec‐alcohols to optically enriched primary amines throught a photo‐biocatalytic ...
