The major products of the photolysis of the oximes of two natural bicyclo[2.2.1]heptanones, (+)-fenchone and(+)-camphor, in methanol are nearly equal amounts of two isomeric lactams arising from the photo-Beckmann rearrangement and the corresponding ring-opened amides.

hydroxylamine-O-sulfonic acid affords the nitrogen insertion product α-camphidone by migration of the methylene group rather than the bridgehead. Since Beckmannrearrangements of trigonal oximes afford bridgehead cleavage products with camphor, an alternative synchronous rearrangement of a tetrahedral intermediate is proposed for this Beckmann-like reaction.
