Dual Lewis Acid Promoted/Visible Light Driven Preparation of Aryl Diazenyl Oxazoles from Isocyanoacetamides and Arylazo Sulfones

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract While arylazo sulfones have been widely applied as arylating agents, their exploitation for diazenylation reactions has been previously limited to electron‐rich alkenes such as styrenes and silyl enol ethers. Herein we optimized a synthetic one‐pot protocol to access oxazolyl azo compounds via a selective domino ring‐closing/aryldiazenylation ...

Improving the Photochemical Skeletal Enlargement of Pyridines to 1,2‐Diazepines with Isocyanates

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract In this work, we extend the one‐pot protocol to synthesize 1,2‐diazepines from commercially available and cheap starting materials. Capitalizing on isocyanate derivatives as activating agents, the photochemical skeletal enlargement occurs, while preserving key functional groups embedded in more than 30 substrates.

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

open access: yesAdvanced 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

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract 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.
