  Synthesis of Bicyclic Dioxetanes Bearing a 4-(Benzimidazol-2-yl)-3-hydroxyphenyl Group and Their Base-Induced Chemiluminescent Decomposition in an Aprotic Medium and in an Aqueous Medium

  摘要：

  Bicyclic dioxetane, 5-tert-butyl-4,4-dimethyl-2,6,7-trioxabicyclo[3.2.0]heptane, bearing a 4-(benzimidazol-2-yl)-3-hydroxyphenyl group at the 1-position and its N-substituted benzimidazolyl-analogs were synthesized. N-Methylbenzimidazolyl-analog and N-phenylbenzimidazolyl-analog were found to undergo charge-transfer-induced decomposition (CTID) to effectively give light in both TBAF/MeCN and in NaOH/H2O. The CTID of N-(4-carboxybutyl)benzimidazolyl-analog gave also effectively light both in MeCN and in H2O. On the other hand, chemiluminescent CTID of the unsubstituted benzimidazolyl-analog changed depending on the base used: TBAF/MeCN induced weak emission of yellow light due to a dianion of the dioxetane, while TMG(tetramethylguanidine)/MeCN induced strong emission of blue light due to a monoanion of the dioxetane.

  Base-induced decomposition (BID) of bicyclic dioxetanes bearing a 3-hydroxyphenyl substituted with 4-p-oligophenylene moiety proceeded rapidly to give bright light even in water as well as in acetonitrile or DMSO. Addition of β-MCD (methylated β-cyclodextrin) or TBHP (tributylhexadecylphosphonium bromide) to an aqueous system improved chemiluminescence efficiency of these dioxetanes. However, β-MCD

  带有3-对羟基苯并被4-对-低聚亚苯基部分取代的双环二氧杂环丁烷的碱诱导分解（BID）迅速进行，即使在水以及乙腈或DMSO中也能发出明亮的光。将β-MCD（甲基化的β-环糊精）或TBHP（三丁基十六烷基溴化phosph）添加到水性体系中可改善这些二氧杂环丁烷的化学发光效率。然而，β-MCD在不降低BID发生率的情况下起作用，而TBHP大大降低了发生率。
