4,6-Dichloro-2-oxa-5-azabicyclo[2.2.2]oct-5-en-3-ones and their Use in the Synthesis of 1,6-Dihydro-6-oxo-2-pyridine- and 6-Oxo-2-piperidinecarboxylates
摘要:
4,6-Dichloro-2-oxa-5-azabicyclo[2.2.2]oct-5-en-3-ones obtained from cycloaddition of 2H-1,4-oxazin-2-ones and alkene compounds, undergo lactone cleavage with alcohols to yield 1,4,5,6-tetrahydro-5-hydroxy-6-oxo-2-pyridnecarboxylates which can be dehydrated or reduced to a afford 1,6-dihydro-6-oxo-2-pyridine- or 6-oxo-2-pipcridinecarboxylates.
