A second‐generation synthesis of the rearranged spongian diterpene aplyviolene is reported. The key step is the addition of a trialkyl tertiaryradical generated by photoredox‐mediated fragmentation of a N‐(acyloxy)phthalimide to an α‐chloropentenone (see scheme). This process fashioned a quaternary stereocenter while combining two units of significant complexity.
