The (2-quinolylmethyl)- and (1-isoquinolylmethyl)ketoximes 2a-e and 4a-d have been prepared and the oxime configurations determined.The Pyrazoloquinolines 7a, b and the pyrazoloisoquinoline 8a are formed by Beckmann reaction of the anti-isomers 2a, b and 4a, while O-mesitylsulfonylhydroxylamine yields the pyrazolo compounds 7 and 8, independent of the oxime configuration.
