Asymmetric azidohydroxylation of styrene derivatives mediated by a biomimetic styrene monooxygenase enzymatic cascade [PDF]
, 2021 Enantioenriched azido alcohols are precursors for valuable chiral aziridines and 1,2-amino alcohols, however their chiral substituted analogues are difficult to access. We established a cascade for the asymmetric azidohydroxylation of styrene derivatives

Advanced Synthesis &Catalysis, Volume 367, Issue 24, December 22, 2025.This article reports an electrosynthetic method for vicinal trifluoromethylchlorosulfonylation of alkenes using [Cu(MeCN)4]PF6 and triethylamine, without elaborate ligands. The reaction efficiently adds CF3 and SO2Cl across diverse unactivated alkenes with broad functional group tolerance.

Advanced Synthesis &Catalysis, Volume 367, Issue 15, August 26, 2025.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

Chemo-, Diastero-, and Regioselective C−c and C−o Bond formation via Transition Metal Catalysis [PDF]
, 2015 The efficient stereoselective formation of C−C and C−O bonds remains a critical challenge in organic chemistry. The level difficulty of these bond formations increases dramatically when regio-, diastereo-, and chemoselectivity issues are present.
