• Synthesis and Carbonic Anhydrase Inhibitory Activity of 4-Substituted 2-Thiophenesulfonamides

  A series of 4-substituted 2-thiophenesulfonamides was prepared from 3-thiophenecarboxaldehyde using metalation chemistry developed for 3-furaldehyde. Several of these compounds inhibit carbonic anhydrase II in vitro at concentrations of less than 10 nM. In addition, none of these compounds exhibit sensitization potential as determined from in vitro measurement of cysteine reactivity.

  日期：1994.8

  AbstractThe processes leading to the fragment ions formed from alkylthiophene molecule ions by benzylic cleavage without and with transfer of one hydrogen from the side‐chain to the ring and the influence of additional methyl groups on the relative importance of these two fragmentation reactions were investigated.
• Bridged Dithienylethylenes as Precursors of Small Bandgap Electrogenerated Conjugated Polymers

  Bridged dithienylethylenes (DTEs) bearing solubilizing alkyl chains at various positions (2-5) have been synthesized by McMurry dimerization of cyclopenta[b]thiophen-6-ones. In order to introduce alkyl substituents at different positions of the DTE molecule, the precursor ketones have been prepared by different strategies based on a combination of Mannich or Wittig-Horner reaction and Friedel-Craft intramolecular cyclization. The position and the length of the alkyl substituents exert a strong effect on the ability of the precursor to undergo electrochemical polymerization. Thus, whereas substitution at the alpha-position of the ethylene linkage (3) results in a rapid inhibition of electropolymerization, introduction of alkyl chains at the beta-position (4, 5) greatly improves the efficiency of the polymerization process. The analysis of the electrochemical and optical properties of the polymers shows that rigidification of the DTE molecule leads to a significant decrease of the oxidation potential and bandgap. A comparative analysis of DTE and its bridged analogues by means of X-ray diffraction reveals, in agreement with experimental and theoretical results, that the observed reduction of both the HOMO-LUMO gap of the precursor and the bandgap of the corresponding polymers are related to a relaxation of bond length alternation in the DTE moiety.
• A remarkable effect of ionic liquids in transition-metal-free aerobic oxidation of benzylic alcohols

  The transition-metal-free aerobic oxidation of benzylic alcohols is uniquely accelerated by a 1-butyl-3-methylimidazolium hexafluorophosphate (BMI-PF(6))/PhCF(3) biphasic system and Cs(2)CO(3) to afford the corresponding ketones in good yields. The reaction system is also applicable to an oxidative cross-esterification of primary benzyl alcohols with a higher aliphatic alcohol. (C) 2011 Elsevier Ltd. All rights reserved.

  X-Ray structure analysis of a new rigid dithienylethylene shows that the observed reduction of the HOMO–LUMO gap results from a relaxation of bond length alternation.
