Energy-Transfer-Driven[2 + 2] Cycloaddition: Synthesisof Cyclobutane-Fused Tetracycles from Indenes and Maleimides

Abstract Molecular skeletons containing fused cyclobutane rings are of significant value in drug discovery as they can increase the fraction of sp3 carbons (Fsp3) and impart conformational rigidity. Herein, we report a visible-light photocatalytic strategy for the intermolecular...
