NOVEL COMPOUND FOR ORGANIC ELECTROLUMINESCENT DEVICE AND ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING THE SAME

Provided are a compound for an organic light emitting device and an organic light emitting device comprising the same. To this end, it is possible to provide a compound for an organic light emitting device which can be used as a host, a hole-transport material, or an electron-transport material capable of enhancing light-emitting efficiency of phosphorescent light-emitting materials by having outstanding electrical stability, an electron and hole transportability, and a high level of triplet state energy, and the organic light emitting device.

Dienophilicity of imidazole in inverse electron demand Diels-Alder reactions: Cycloadditions with 1,2,4,5-tetrazines and the structure of zarzissine

The inverse electron demand cycloadditions of 2-substituted imidazoles with dimethyl 1,2,4,5-tetrazine-3,6-dicarboxylate produced imidazo[4,5-d]pyridazines in good yields. This chemistry was applied to the synthesis of 2-amino-1H-imidazo[4,5-d]pyridazine (1), the structure reported for zarzissine, a cytotoxic marine alkaloid. Differences in the 1H- and 13C NMR spectra of 1 with those reported for zarzissine necessitated a structural revision, and zarzissine was then considered to be the corresponding 2-amino-1H-imidazo[4,5-b]pyrazine (2), which was subsequently synthesized from the parent heterocycle.
