Abstract: 3-Nitro-4-chloroquinoline 3 was converted to the azides 5/6. The azides were cyclized on thermolysis to furoxanes 7/8. Deoxygenation to furazane 9 was achieved by reaction with triphenylphosphane. The reaction conditions were studied by differential scanning calorimetry (DSC). The azides 5/6 gave with triphenylphosphane the phosphazenes 10/11, which were cleaved to the aminoquinolone 12
