Oxidation of 2-phenyl-1-oxa-9-azabicyclo<4.3.0>nonane (5) with m-chloroperoxybenzoic acid is not regioselective, in contrast to the case with the corresponding 1-oxa-8-azabicyclo<3.3.0>octane (2; n = 1, R1 = H, R2 = Ph), affording mainly the keto-nitrone (7).On reaction with styrene in boiling toluene the latter forms the oxabicyclononane (9).
