Angewandte Chemie, EarlyView.Cyclopropanols undergo palladium‐catalyzed, zinc‐mediated allylation with allyl acetates: the ring opens transiently to an enolized homoenolate, is intercepted by π‐allylpalladium, and recloses to furnish β‐allylated cyclopropanols. This formal “allylic cyclopropylation” broadens the reaction space for ring‐retentive functionalization of cyclopropanols.

Flavin Catalysts in Organic Synthesis
Angewandte Chemie, EarlyView.Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.
