Abstract
The reaction of ethyl 5-oxo-2,5-dihydroisoxzole-4-carboxylate with derivatives of 2-chloroquinoline afforded the desired N-quinolinyl isoxazolones. Their reactions with triethylamine in chloroform produced the corresponding pyrimidoquinoline derivatives, through intramolecular cyclization.
