A reviewer has suggested that a Li-π-naphthalene coordination might be responsible for the preferred conformation of the stereocontrolling group. In a simple calculation, it was found that the cyclohexene ring in the dianion is not planar and pseudoaxial hydrogens may also contribute to the direction of electrophilic attack. We thank the reviewer for this suggestion
