We exhibit the first example of constructing high ordered macroporous silica adsorbent by using a low-cost silica source. This silica-based macroporous material can be useful as a powerful separation tool to deal with environmental pollution because it is easy to separate simply by centrifugation without any modification. Interestingly, the absorption and separation for neutral red show that it can increase absorbent amount of dye and decrease the rate of dye desorbed in comparison to conventional hollow silica obtained via the Stöber method.

Structures of 4-Iminopyrido[1,2-a]pyrimidines, Pyrido[1,2-a]pyrimidin-4-ones, Pyridopyrimidinium Olates, and Thiazolo[3,2-a]pyrimidine Analogues 
Paul V. Bernhardt and Curt Wentrup
pp. 371-375

Extraordinarily long ‘amidine’ and ‘amide’ C–N bonds (up to 1.5 Å) and acute NCX angles in the title compounds are interpreted in terms of the Structure-Correlation Principle of Buergi and Dunitz. The structural features are in accord with the observed thermal ring opening to ketenimines and ketenes, respectively.

Synthesis of Cyclic Carbonate From Carbon Dioxide and Epoxide Using Amino Acid Ionic Liquid Under 1 atm Pressure 
Qing Gong, Huadong Luo, Jin Cao, Yuhan Shang, Haibo Zhang, Wenjing Wang and Xiaohai Zhou
pp. 381-386

The cycloaddition of carbon dioxide into epoxide was realized by using an amino acid ionic liquid. With triethylamine as co-catalyst, the catalytic activity of a l-proline based ionic liquid was greatly enhanced, and up to 97 % isolated yield of cyclic carbonate was achieved. This method affords an alternative access to cyclic carbonate under 1 atm carbon dioxide pressure without metal or solvent.

Hakim Mehenni and Lê H. Dao
pp. 395-401

In this study, a simple and direct biodetector of avidin was proposed, using biotin immobilized onto a conducting polymer-coated electrode based on poly(chloro amino-β-styryl terthiophene). The biotin-avidin interaction was monitored by cyclic voltammetry for the detection of avidin at 4 × 10–6 mol L–1.

 
  
 


 
The Bioreductive Alkylation of DNA by Kalafungin: A Theoretical Investigation 
Paul A. Hume, Margaret A. Brimble and Jóhannes Reynisson
pp. 402-408

The thermochemical cascades for the bioreductive alkylation of DNA by kalafungin were calculated. According to them both one- and two-electron reduction is possible in vivo. Furthermore, a clear pathway was found for both mono- and bis-alkylations of guanine. The results presented here support the idea that this compound readily forms covalent bonds with DNA resulting in pro-mutagenic lesions.

Oxidative Damage of Pyrimidine Nucleosides by the Environmental Free Radical Oxidant NO3 in the Absence and Presence of NO2 and Other Radical and Non-Radical Oxidants 
Catrin Goeschen, Jonathan M. White, Robert W. Gable and Uta Wille
pp. 427-437

Product studies showed that the reaction of the night-time atmospheric free-radical oxidant NO3 with uridine 1 and thymidine 2 is very complex and is influenced by the presence of other free radical species, specifically NO2. Depending on the conditions, the reaction can either lead to cleavage of the glycosidic bond, addition to the C=C double bond, or substitution of R at the nucleobase.
