  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.

  Chemiluminescent decomposition of bicyclic dioxetanes 3a-3c bearing a 4-(N-phenylbenzimidazol-2-yl)-3-hydroxyphenyl moiety was effectively induced by organic superbases, BTPP [(tert-butylimino)tris(pyrrolidino)phosphorene], TBD (1,5,7-triazabicyclo[4.4.0]dec-5-ene), MTBD (7-methyl-1,5,7-tri azabicyclo [4.4.0] dec-5-ene), DBU (1,8-diazabicyclo-[5.4.0]-undec-7-ene), and TMG (tetramethylguanidine), as well as TBAF in acetonitrile. Dioxetane 3c bearing a 3,5-dihydroxyphenyl moiety showed diverse chemiluminescence profiles depending on the base used. BTPP caused chemiluminescent decomposition due to the di-oxido anion of dioxetane, while DBU and TMG induced chemiluminescence from the mono-oxido anion of dioxetane. On the other hand, TBAF caused effective chemiluminescence due to the mono-oxido anion, though it acted as a stronger base than BTPP with regard to the rate of decomposition of 3c.
