Methods for the Synthesis of 4-Azido-2(1H)-quinolones
Stadlbauer, Wolfgang
, p. 1305 - 1324 (2007/10/02)
4-Hydroxy-2-quinolones 1 are generally found to be converted to the 4-azidocompounds 3 via the 4-chloroquinolones 2, the 4-tosyloxyquinolones 6, or the 4-aminoquinolones 4, respectively.Choice of the reaction conditions and yields depend on the substituen
