Abstract
The compounds are amino- or cyano-bearing dihydroquinolines, which have either of the combinations of (a) 2-amino, 3-carboxylic and 4-oxo functions, or (b) 2-oxo, 3-cyano and 4-hydroxy functions, and may be optionally substituted at 1 or 2 of the 5, 6, 7 or 8 positions, eg 1-allyl-2-amino-1,4-dihydro-6,7-dimethoxy-4-oxo-quinoline-3-carboxylic acid ethyl ester, and 1-allyl 3-cyano-1,2-dihydro-4-hydroxy-6,7-dimethoxy-2-oxo-quinoline. The compounds are useful as pharmaceuticals.
