AbstractThis study was aimed at determining the effect, if any, that steric factors may have on the diastereoselectivity in the spiroannulation of simple phenols. A series of phenols bearing different size substituents ortho to the phenolic hydroxyl were synthesized and spiroannulated to the corresponding spiroethers in good to excellent yields (76-94%). However, the diastereoselectivity of the reaction remain mostly unchanged suggesting that stereoelectronic rather then steric factors influence the diastereoselectivity in this reaction.
