  Synthesis and characterization of organotin triflate clusters

  摘要：

  A variety of organotin triflate clusters are obtained by treating dialkyltin oxide with triflic acid (TfOH) in different ratios. When R2SnO is exposed to 0.5 equivalents of TfOH, 3-hydroxy-1-triflato distannoxanes (1) are formed which have a novel sheet-like structure in the solid state. Treatment of R2SnO with 2/3 or one equivalent of TfOH affords a trinuclear cluster 3 or cationic dimers 2. The stoichiometry of the novel trinuclear cluster can be confirmed by various chemical reactions as well as elemental analysis. On the basis of Sn-119-NMR study, the equilibrium has been revealed between 2 and 3. The use of two equivalents of TfOH in the reaction with R2SnO offers a convenient route for R2Sn(OTf)(2) (4).

  Synthesis and evaluation of isoxazole derivatives as lysophosphatidic acid (LPA) antagonists

  摘要：

  A series of isoxazole derivatives were synthesized and their antagonistic activities against LPA stimulation on both LPA(1)/ CHO cells and rHSC cells were evaluated. Among them, 3 -(4-{4- [1 -(2-chloro-cyclopent-1-enyl) -ethoxycarbonylamino] -isoxazol - 3- yl}-benzylsulfanyl)-propionic acid (34) showed the most potent activities. (c) 2007 Elsevier Ltd.

  A flexible synthetic route to the 16-membered tetramate-embedding macrocyclic scaffold present in various polycyclic tetramate macrolactams (PTMs) was developed which differs from the seminal synthesis of ikarugamycin by Boeckman Jr. in protecting groups and the order of connections. We also devised a short approach to various stereoisomers of the 5/5/6-tricarbocyclic motif found in discodermide and

• Synthesis and Structural Studies on Dimeric Organotin Cations

  Novel dimeric organotin cations [R2SnOH(OTf)(H2O)](2) (R = n-Bu, t-Bu, and 2-phenylbutyl; Tf = CF3SO2) were synthesized from R2SnO and TfOH. The structures of these compounds were investigated by single-crystal X-ray analysis and solid-state Sn-119 NMR in the solid state and Sn-119 NMR spectra together with electrical conductivity measurements in solution. tert-Butyltin and 2-phenylbutyltin derivatives have cationic structures both in the solid state and in solution. The n-butyltin derivative is nonionic in the solid state but dissociates into ionic species in solution. The H2O molecule in this compound can be readily replaced by hexamethylphosphoric triamide (HMPA); the resulting adduct has a similar structure. The corresponding nitrate has a nonionic dimeric structure with bidentate nitrate coordination, [t-Bu2SnOH(NO3)](2). As such, it is concluded that both bulky alkyl groups attached on tin and electronegative ligands such as triflate are crucial for generation of the cationic species.
