The aminomethylbicyclanol 3, obtained from the cycloadduct 4 of norbornene (1) and trichloroacetyl isocyanate, furnished the 1,3-oxazin-2-one 7, 1,3-oxazine-2-thione 8 and 1,3-oxazines 2a-d.The exo-exo- (10, 12) and endo-endo-1,3-oxazin-4-ones (11, 13) were prepared from the 3-hydroxy-2-carboxamides 5 and 9.Structure of these rigid tricyclic systems were proved by 1H and 13C NMR spectroscopy.
