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.
