Constant Enzymatic in situ Production of H2O2 for an Unspecific Peroxygenase by an l–Amino Acid Oxidase

Advanced Synthesis &Catalysis, EarlyView.
Abstract 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. In order to prevent the deactivation, we developed an enzyme cascade

Synthesis of spirolactones from carbonyls via carboborylation of N‐sulfonylhydrazones with alkoxycarbonylalkylboronic acids

Advanced Synthesis &Catalysis, Accepted Article.
A straightforward synthesis of spirolactones from carbonyls via N‐tosylhydrazones is described. The process consist in the reaction between the N‐tosylhydrazone and ethoxycarbonylethylboronic acid or ethoxycarbonylpropylboronic acid, leading to spiro γ‐butyrolactones or δ‐valerolactones respectively. The transformation takes place by carboborylation of

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 ...

Development of Hydrofluoroolefin (HFO)‐based direct O‐fluoroalkenylation of phenols targeting tyrosine conjugation

Advanced Synthesis &Catalysis, Accepted Article.
Methodology for direct fluoroalkenylation of phenolic OH function was developed using a fluorinated electrophilic reagent derived from HFO1234ze gas. Besides various functionalized phenols, tyrosine and tyrosine‐based peptides were successfully conjugated under the optimized reaction conditions.
