Several cyclicα,β-unsaturated ketoximes, or their tosylates were subjected to the Beckmannrearrangement. With all compounds except 8b, groups located anti to the leaving group migrated efficiently, irrespective as to whether the migrating group was alkyl or olefinic. The olefinic group in 8b, however, resisted the migration and this was interpreted in terms of the steric effect in the transition
