Reaction with hydrazones

Ring Synthesis of IR-Indazoles, 1,2-Benzisothiazoles and 1,2-Benzisoxazoles The earliest syntheses of 1,2-benzisoxazoles depended on the cycUsation of an ortfto-haloary 1-ketone oxime, typical conditions are shown below and involve an intramolecnlar nncleophilic substitution of the halide. Only one geometrical isomer of the oxime will ring close. Applying this approach to amidoximes is easier, because the two imine geometrical isomers in such compounds are easily interconvertible. Comparable reaction with hydrazones produces indazoles. ... [Pg.509]
