arylboration of cyclopentenes is disclosed. The reaction allows for the synthesis of sterically congested cyclopentane scaffolds that contain an easily derivatized boronic ester and amide functional handles. The nature of the amide directing group and its influence on the reactionoutcome are investigated and ultimately reflect a predictably selective reaction based on the solvent and base counterion.

report a palladium-catalyzed hydroalkoxycarbonylation and hydroxycarbonylation of cyclopent-3-en-1-ols to form bridged bicyclic lactones and β,γ-unsaturated carboxylic acid. The divergent reactivity of cyclopent-3-en-1-ols is mainly tuned by the palladium catalyst and ligands. The reaction occurs additive-free and has a broad substrate scope. Several valuable synthetic and medical intermediates are accessible
