Photocatalytic Polyene Cyclization to Cyclopentyl Thioethers with Consecutive Quaternary Centers in Fluorinated Alcohols

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A photocatalytic strategy enables efficient cyclization of polyenes to cyclopentyl thioethers with consecutive all‐carbon quaternary centers. Using 2,4,6‐triphenylpyrylium tetrafluoroborate in 1,1,1,3,3,3‐hexafluoroisopropanol, the method proceeds via a thiyl radical mechanism, offering high yields and good diastereoselectivities.

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

open access: yesAdvanced 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
