[Structure: see text] The conjugateadditions of different carbon nucleophiles to cyclopentadienone substrates (1 and 2) with one free hydroxyl functional group were investigated to determine the role of the hydroxylgroup in controlling regiochemistry. During this reaction an unexpected intramolecular displacement of OTBS by the enolate intermediate occurs, to afford cyclopropane derivatives.
