Sažetak
1,2-Oxazine N-oxide condensed heterocycles have been prepared
from (E)-1-phenyl-2-nitropropene and enamines derived from 1-methyl-4-piperidone, 4H-tetrahydro-pyran-4-one and 4H- tetrahydro-thiapyran-4-one. They are more stable than the analogous systems derived from cyclohexanone enamines and just like them they are in equilibrium with their open-chain isomers.
