  从O-抗原的五糖重复单元的会聚化学合成大肠杆菌O158 †

  摘要：

  据报道，通过融合[3 + 2]策略从大肠杆菌O158合成O抗原的五糖重复单元。关键的β-ManNAc部分的合成是由β-Glc衍生物通过叠氮化物亲核试剂将2-位转化而得，且收率很高。非还原性末端二糖α- D- Gal-（1→3）-β- D- GlcNAc是通过硫代糖苷Gal供体的化学选择性活化而形成的。后期TEMPO介导的氧化用于安装所需的糖醛酸部分。在H 2 SO 4-二氧化硅存在下，通过使用NIS活化硫糖苷来完成所需的糖基化反应，具有良好或优异的收率和立体选择性。

  The preparation of RuL3 (1), RuL2L’ (2) and Ru(pod) (3) complexes containing polyethylene glycol chains is described. The complexes are further functionalized by 4-oxyanisyl or by hydrophilic hydroxyl groups. These new complexes may interact in supramolecular assemblies with suitable acceptors such as mono- and bisviologens to form biomimetic models for photosynthesis.

• Photoinduced Electron Transfer in Supramolecular Assemblies Composed of Dialkoxybenzene-Tethered Ruthenium(II) Trisbipyridine and Bipyridinium Salts

  Ruthenium(II) tris4,4'n-bis[(methyleneoxy)tris(ethyleneoxy)(4-methoxybenzene)]-2,2'-bipyridine}(1), forms supramolecular complexes with N,N'-dimethyl-4,4'-bipyridinium, MV(2+) (2), and with cyclo[bis(N,N'-p-xylylene-4,4'-bipyridinium)], BXV(4+) (3). The association constants of the complexes generated between the dialkoxybenzenetethered units of 1 and the electron accepters 2 and 3 correspond to K-a = 28 +/- 1 M(-1) for MV(2+) and K-a = 1200 +/- 100 M(-1) for BXV(4+), Time-resolved laser flash photolysis and steady-state emission studies show that electron transfer from excited 1 proceeds by an intramolecular pathway to the electron accepters organized in the supramolecular assemblies, k(iq) = 1.7 X 10(8) s(-1) for MV(2+) and k(iq) = 2.9 X 10(8) s(-1) for BXV(4+), and by a diffusional route from free-uncomplexed 1, k(dq) = 1.9 X 10(8) M(-1) S-1 for MV(2+) and k(dq) = 3.4 x 10(8) M(-1) s(-1) for BXV(4+). Formation of the supramolecular assemblies between 1 and 2 or 3 is supported by the intramolecular electron-transfer quenching of 1 and by the fact that the assemblies dissociate upon addition of beta-cyclodextrin.
• Photoactive [2]Rotaxanes: Structure and Photophysical Properties of Anthracene- and Ferrocene-Stoppered [2]Rotaxanes
  作者：Andrew C. Benniston、Anthony Harriman、Vincent M. Lynch

  DOI：10.1021/ja00124a010

  日期：1995.5

  The structures of several one- and two-station [2]rotaxanes have been probed in both solid and solution phases. It is shown that the cyclophane, comprising two 4,4'-bipyridinium dications Linked via 1,4-xylyl groups, resides preferentially over a dialkoxybenzene subunit incorporated into the ''string''. The terminal stoppers, anthracene or ferrocene subunits, associate with the exterior of the cyclophane, via pi-stacking, so as to form closed conformations. Excitation into the anthracene stoppers is followed by rapid, but reversible, electron transfer to the cyclophane. Direct excitation into the charge-transfer absorption band results in formation of an intimate radical ion pair in which an electron has been transferred from the central dialkoxybenzene donor to the cyclophane acceptor. Rapid charge recombination occurs but can be partially intercepted by hole transfer to an appended ferrocene stopper. In this latter case, the ground state is restored by relatively slow electron transfer from the reduced cyclophane to the terminal ferrocenium cation. It is proposed that the closed conformation unwinds subsequent to this second electron-transfer step in order to minimize electrostatic repulsion. To some extent, therefore, the rates of electron transfer are controlled by conformational exchange.
