Interaction of 6,7-dichloroquinoline-5,8-dione with amides in ethylene glycol afforded oxazolo[4,5-g]quinoline-4,9-dione, a compound with activity against Gram-positive bacteria (no data) (90MI2). [Pg.199]

Compounds with two oxo groups in the oxazolidine ring have been prepared. Thus, 3,4-dihydro-2(l//)-quinolinones react with oxalyl chloride to form 5H-oxazolo[3,2-a Quinoline-1,2-diones (260) (70M383). [Pg.664]
