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

Advanced 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.

Enzymatic Synthesis of Enantiopure (R)‐Citronellal from Geraniol via a Short‐Chain Dehydrogenase and Ene Reductase

Advanced Synthesis &Catalysis, EarlyView.
A synthetic cascade with two consecutive biocatalytic steps consisting of a short‐chain alcohol dehydrogenase and an ene reductase in a biphasic system provides (R)‐citronellal with >90% conversion and >99% enantiomeric excess from inexpensive geraniol. The development of synthetic routes to produce enantiopure (R)‐citronellal as a key intermediate for

Deazaflavin‐Catalyzed Arylation of White Phosphorus with Aryl Bromides and Chlorides

Advanced Synthesis &Catalysis, EarlyView.
The 5‐aryldeazaflavin photocatalyst o‐Me‐dFl catalyzes the arylation of white phosphorus with aryl chlorides and bromides under near UV‐LED irradiation, affording triarylphosphines and tetraarylphosphonium salts. Nuclear magnetic resonance studies and density functional theory calculations offer insights into the reaction pathway.
