    • During the preparation of this manuscript, we were pleased to find that in 1980, Rosenberger had questioned Hiyama's results and suggested that 11 may be the cause of the observed specific rotation. Their proof was not unequivocal however and their work pre-dated that of Zhang et al. Rosenberger's work does not appear in a Scifinder Scholar search for papers which cite Hiyama's work (although it does in a Web of Science search)-which has no doubt contributed to a general misconception that the results outlined in Ref. 6 are still valid, see:
