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