Abstract
The incorporation of the common tetrasubstituted benzene ring II between two rigid bisphosphonate spirobiindane units gives rise to two diastereoisomers macrobicyclophanes VA and VB in high yield. The structures of these two diastereomers were assigned by 1-D and 2-D NMR. Both products shown a structure were the benzene ring is sandwiched between the cyclic frames to form a chiral molecular 'hamburger'.
