C32H37NO3S, Mr=515.2, monoclinic, P21/c, a=14.8226 (6), b=10.7633 (4), c=18.5221 (8), Angstroem, β=99.71 (1) deg, V=2912.7 (3) Angstroem3, Z=4, Dc=1.176, Dm=1.17 (1) Mg m-3.The structure was solved by direct methods and converged to a conventional R of 0.074 for the 335 parameters varied and 3391 reflections used in the refinement.With respect to the tricyclooctane portion of the molecule the tert-butoxy group at bridgehead position 8 is anti to the phenyl group at position 3, and the contact distance between a bridgehead C and the nearest phenyl carbon C(20) capable of participating in a long-range aryl migration is 2.916 (6) Angstroem.

Effect of Remote Substituents upon the Long-Range Aryl Migration and Electrocyclic Ring Opening of exo-3,3-Diaryltricyclo2,4>octan-anti-8-yl Tosylates in Solvolysis

The processes of long-range aryl migration (LRAM) and electrocyclic ring opening (ERO) that occur in the solvolysis of the title substrates have been investigated with respect to their relative timing.By substituting an electron-withdrawing group (CN) or
