Recent studies have shown that energy transfer photoenzymes can be engineered to promote stereocontrolled [2 + 2] cycloadditions; however, existing systems rely on ultraviolet light and display limited photochemical efficiencies. A generation of thioxanthone-containing photoenzymes now harnesses visible light to drive challenging photochemical conversions with high efficiencies and selectivities.
