## Abstract A vinylogous pinacol–pinacolone rearrangement is reported that takes place although the two hydroxyl groups are formally separated by seven bonds. It involves a transannular hydride shift that occurs between the benzylic positions of the __pseudo‐geminally__ substituted [2.2]paracycloph
## Abstract Synthetic routes to __pseudo‐geminal__, __pseudo‐ortho__ and __ortho__ hydroxy‐oxazolinyl[2.2]paracyclophanes (and the diastereoisomers of each) for use as N,O ligands in asymmetric catalysis have been devised. The substitution pattern was found to have a strong effect on the rate and e
