Abstract
Diamide-calix[4]crown-4-ether 3, diester-calix[4]crown-4-ether 5 and calix[ 4]crown-4-ether 7 were conveniently oxidized by sodium perborate tetrahydra te in trifluoroacetic acid to afford the diquinone 4 and 6 and monoquinone 8, respectively. The structures of the calix[4]quinones were established by IR, MS, H-1 NMR, C-13 NMR and elemental analysis.
