As potential chemiluminescent probe for singlet oxygen, the furonaphthalimide 4 was synthesized in five steps (ca. 25% overall yield), by starting from commercially available 4-chloro-1,8-naphthalic anhydride; its photooxygenation at −10°C gave the cleavage product 6 of the intermediary dioxetane 5, which is thermally too labile for isolation and could not be detected even by low temperature NMR spectroscopy
作为潜在的单线态氧化学发光探针,呋喃邻苯二甲酰亚胺4由五步合成(总收率约25%),是从市售的4-氯-1,8-萘酐开始合成的。其在-10°C的光氧化作用产生了中间体二氧杂环丁烷5的裂解产物6,该裂解产物热不稳定,无法分离,即使通过低温NMR光谱也无法检测到。完全表征了新的1,8-萘二甲酰亚胺衍生物3、4和6,并确定了它们的吸收和荧光光谱性质。
