Abstract

Abstract Die (2-Chinolylmethyl)-und (1-Isochinolylmethyl) ketoxime 2a-e und 4a-d wurden synthetisiert und die Oximkonfigurationen ermittelt. Durch Beckmann-Reaktion entstehen aus den anti-Isomeren 2a, b und 4a die Pyrazolo [1, 5-a] chinoline 7a, b bzw. das Pyrazolo [5, 1-a] isochinolin 8a, während mit O-Mesitylsulfonylhydroxylamin die Pyrazoloverbindungen 7 und 8 unabhängig von der Oximkonfiguration entstehen.
