This method constitutes a novel approach to the challenging 1,6-dioxygenation motif. A range of γ-substituted enones, including many bearing all-carbon quaternary centers, are available through a simple protocol under mild reaction conditions with superb functional group compatibility. Excellent stereoinduction is observed providing controlled access to challenging stereochemical arrays.

Visible-light photoredox catalysis enables the vinylation and allylation of electrophilic radicals with readily available potassium trifluoroborate reagents. The processes show good functional group compatibility, and mechanistic and computational studies have elucidated some of the aspects associated with the key radical addition step.
