✦ Synopsis


We wish to report the synthesis of the title compound (III), which is the first'reported 2.2 metacyclophane with substituents on the side chain3 CI and. by virtue of its conformation is also the first c3 2.2 metacyclophane in which H8 and H16 are magnetically non-equivalent.

is synthesised. Variable temperature 1Hmr and 13Cmr spectra indicate that4e is the most likely conformation and that at temperatures above 50Β°C the molecule is fluxional (AGATE = 15.4 kcal/mole).
