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.

Visible Light‐Promoted Esterification of Carboxylic Acids via Photoacid Generation Catalysis

Advanced Synthesis &Catalysis, EarlyView.
A novel, environmentally friendly photochemical method for the esterification of carboxylic acids with alcohols using arylazo sulfones as photoacid generators was developed. This approach avoids traditional acidic catalysts, purification did not require chromatography and the method proved effective under continuous flow conditions for enhanced ...

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 ...

Integrating Visible‐Light Photocatalysis and Enzymes for the Stereoselective Synthesis of Alcohols and Amines

Advanced Synthesis &Catalysis, EarlyView.
The integration between visible‐light photocatalysis and biocatalysis has the potential to greatly improve modern organic synthesis by combining the production of valuable synthetic intermediates under mild photochemical conditions with the high degree of stereoselectivity reached by enzymes. The review collects the recent efforts in the photoenzymatic
