Quinoxalinecarboxamides and Related Derivatives

Quinoxalinecarboxamides have added interest in that some complicated derivatives occur naturally. Thus quinoxapeptin A and B were isolated from a bark disk [Pg.334]

Several reactions of quinoxalinecarboxamides and related derivatives have been discussed already the Hofmann or Curtius degradation to quinoxalinamines (Section 6.3.1), hydrolysis to quinoxalinecarboxylic acids (Section 7.1.1), and... [Pg.337]

Several recent general papers on the properties of quinoxaline N-oxides have reported studies on the crystal structures of quinoxaline 1,4-dioxide,380 its 2,3-dimethyl derivative,380 ethyl 7-chloro-3-methyl-2-quinoxalinecarboxylate 1,4-dioxide,40 and N-(2-hydroxyethyl)-3-methyl-2-quinoxalinecarboxamide 1,4-dioxide 931 the NMR spectral data of quinoxaline 1,4-dioxide for comparison with those of related dioxides 348 the NMR data for biologically active quinoxalinecarboxamide dioxides 381 thermochemical data for several quinoxaline dioxides 183 and polaro-graphic or cyclic voltammetric data for 2,3-disubstituted quinoxaline dioxides.239 894... [Pg.230]
