rac-4-bromo-[2.2]paracyclophane and rac-trifluoromethanesulfonic acid (4-[2.2]paracyclophane) ester was performed with high diastereoselectivities. Kinetic racemic resolution of the starting materials was achieved, providing a rapid access to enantiomerically enriched 4-bromo-[2.2]paracyclophane and the corresponding enantiomerically pure [2.2]paracyclophane amines. Additionally, the first reaction of a secondary

A regioselective formylation of N-substituted 4-amino[2.2]paracyclophanes is described, which allows an easy access to key synthetic intermediates which are useful for the preparation of a large variety of para di-substituted paracyclophanes in a straightforward manner.
