A three-component condensation of 1-allyl-4-hydroxy-2-oxo-1,2- dihydroquinoline, isatin, and malononitrile gave a satisfactory yield of 4,3′-spiro[(6-allyl-2-amino-5-oxo-5,6-dihydro-4H-pyrano-[3,2-c] quinoline-3-carbonitrile)-2′-oxindole], which structure was confirmed by X-ray analysis.

Bromination of N-allyl-4-hydroxy-2-oxo-1,2-dihydroquinoline and N-allyl-5-ethoxycarbonyl-4-hydroxy-6-methyl-2-oxo-1,2-dihydropyridine is accompanied not only by closing of a five membered oxazole ring but also by a second bromination of the 2-bromomethyl-5-oxo-1,2-dihydro-5H-oxazolo[3,2-a]- derivatives formed at position 4.
