| Description |
The Pd-C-assisted hydrogenolysis of substituted 3-(2-nitrophenyl)-isoxazoles, irrespective of substitution on the isoxa-zole ring, invariably leads to reduction of nitro to amino group with concomitant regiospecific ring closure to yield substituted 4-quinolinamines. In contrast similar hydrogenation of 3-(nitro substituted phenyl)-2-isoxazolines results in reduction of the nitro group only with conservation of isoxazoline ring to yield 3-(amino substituted phenyl)-2-isoxazolines.
