Abstract: | 4-Hydroxy-2-quinolones1 are generally found to be converted to the 4-azidocompounds3
via the 4-chloroquinolones2, the 4-tosyloxyquinolones6, or the 4-aminoquinolones4, respectively. Choice of the reaction conditions and yields depend on the substituent in position 3 of the quinoline nucleus. For comparison the O-analogous coumarin derivatives9 have been studied to give the 4-azidoderivatives11
via the 4-chlorocoumarins10. |
