Abstract:
A series of new 5H-pyridobenzazepine and pyridobenzothiepine derivatives was synthesized by Pd-catalyzed formation of C-N and C-S bonds. All synthesized compounds were tested for their in vitro antimicrobial activity. The 5H-pyridobenzazepine derivatives showed better antibacterial and antifungal activity than corresponding 5H-dipyridoazepine analogs. Among the synthesized azepines, derivative 8 displayed potent activity against tested bacteria (MIC = 39-78 ?g/mL), while azepine 12 showed promising antifungal activity (MIC = 156-313 ?g/mL). The synthesized thiepine derivatives exhibited weak antibacterial activity, but showed pronounced antifungal activity.

Abstract:
The homologous series of three-atom bridged biaryls comprising 5,7-dihydro-1,2,3,9,10,11-hexamethoxydibenzo[c,e]oxepine, 6,7-dihydro-1,2,3,9,10,11-hexamethoxy-6-methyl-5H-dibenzo[c,e]azepinium chloride, 5,7-dihydro-1,2,3,9,10,11-hexamethoxydibenzo[c,e]thiepine, and the 6-oxide and 6,6-dioxide derivatives of the latter have been characterized by X-ray crystal structure analysis. Within this series the endocyclic and exocyclic biaryl dihedral angles vary over 10° ranges, reflecting the changing balance of intramolecular (steric, geometric) and intermolecular (crystal packing) forces, the former being potential control elements for fine-tuning the helicity of the biaryl system.

Abstract:
The validity of a new dopamine D-2 receptor interaction model based on conformational analysis and least-squares superimposition studies of the indan derivative tefludazine and the thiepin derivative octoclothepin was further tested by comparison of the effect of aromatic substitution on D-2 antagonistic activity in two series of indan and thiepin derivatives. The indan series include new derivatives substituted in the 4-, 7-, 2’- and 3’-position. The substitution effects were largely parallel with one important exception: Only 6-substituted indans have significant neuroleptic activity while both 8- and 7-substituted thiepin derivatives have neuroleptic activity. In indans additional fluorination in the 2’- or 4’-position is demanded to give potent neuroleptic activity, while a 3’-fluoro-substituted derivative was inactive. Fluorination is not necessary in thiepins although 3-fluoro derivatives have a significant prolonged duration of action. Considering the differences in physico-chemical properties, metabolism and pharmacokinetics between the two series, the largely parallel substitution effects support the new D-2 receptor model.

Abstract:
This research project is concentrated on tuning the properties of small organic molecules, namely polyacenes, tropones and thiepins, by incorporating redox-active transition metal centers π-bonded to terminal cyclopentadienyl ligands. Organometallic-fused acenequinones, tropones, thiepins and cyclopentadiene-capped polyacenes were synthesized and characterized. This work was divided into three parts: first, the synthesis of ferrocene-fused acenequinones, cyclopentadiene-capped acenequinones and their subsequent aromatization to polyacenes; second, the synthesis of ferrocene-fused tropones, thiotropones and tropone oxime; and third, the synthesis of ferrocene-fused thiepins. Ferrocene-fused quinones are the precursors to our target complexes. Our synthetic route to ferrocenequinones involved two-fold aldol condensation between 1,2-diformylferrocene and naphthalene-1,4-diol or anthracene-1,4-diol, and four-fold condensation between 1,2-diformylferrocene and 1,4-cyclohexanedione. Reduction of ferrocene-fused quinones with borane in THF resulted in ferrocene-fused dihydroacenes. Attempts to reduce ferrocene-fused acenequinones with sodium dithionite led to metal-free cyclopentadiene- (Cp-) capped acenequinones. Cp-capped acenequinones were aromatized to bis(triisopropylsilyl)ethynyl polyacenes by using lithium (triisopropylsilyl)acetylide (TIPSC≡CLi) with subsequent dehydroxylation by stannous chloride. The compounds were characterized by using spectroscopic methods and X-ray crystallography. Further, the electronic properties of these compounds were studied by using cyclic voltammetry and UV-visible spectroscopy. Cyclic voltammetry showed oxidation potentials of Cp-capped TIPS-tetracene and bis-Cp-capped TIPS-anthracene as 0.49 V and 0.61 V, respectively (vs. ferrocene/ferrocenium). The electrochemical band gaps were 2.15 eV and 2.58 eV, respectively. Organic thin-film transistor device performance of Cp-capped polyacenes was studied using solution deposition bottom-contact, bottom-gate (BCBG) device architecture and the resulting performance parameters are described herein. Similarly, we are also interested in potential applications of metallocene-fused tropones and derivatives as organic electronic materials. Condensation of 1,2-diformylferrocene with acetone or 1,3-diphenylacetone in the presence of KOH resulted in the ferrocene-fused tropone (η5-2,4-cyclopentadien-1-yl)[(1,2,3,3a,8a-η)-1,6-dihydro-6-oxo-1-azulenyl]iron (1, R = H, E = O) and its 5,7-diphenyl derivative (1, R = Ph, E = O) as previously reported by Tirouflet. The use of piperidine as base resulted in Michael addition of piperidine to one of the carbon-carbon double bonds of the tropones. Lawesson’s reagent converted the ferrocene-fused tropones to either a thiotropone (1, R = H, E = S) or a detached 5,7-diphenylazulenethiol (2). Reaction of the ferrocene-fused thiotropone with hydroxylamine gave the corresponding oxime (1, R = H, E = NOH). Products were characterized by using spectroscopic methods and X-ray crystallography. Their electronic properties were studied by using cyclic voltammetry and UV-visible spectroscopy. The third project involved the two-fold aldol condensation of 1,2-diformylferrocene with dimethylthioglycolate S-oxide in the presence of freshly distilled triethylamine, which gave mono- and di-dehydrated products. Deoxygenation of the ferrocene-fused thiepin S-oxide with 2-chloro-1,3,2-benzodioxaphosphole in the presence of pyridine resulted in the corresponding thiepin. The ester groups of the thiepin and thiepin S-oxide were hydrolyzed under basic conditions to give carboxylic acids, which were converted into acid chlorides using oxalyl chloride. Attempts to decarboxylate the thiepin and thiepin S-oxide diacids resulted in decomposition.

Glycosidases play an important role in metabolism. Many diseases related to glycosidase, such as cancer, diabetes , HIV, etc. In this article, the seven-memberd ring thiosugars, so-called thiepanes, were synthesized in order to evalute them as inhibitors. Their structures are more flexible than the other thiosugars such as thiopenes and thiopyranes. Salacinol isolated from Salacia reticulate, possessed zwitterionic structure which is similar to the oxonium ion. Many salacinol analogues were synthesized as glycosidase inhibitors and they showed great biological activities. We have synthesized 7-(hydroxymethyl)-3,4,5-trihydroxyazepanes as potential glycosidase inhibiors. Based on the similar strategy, we synthesized a series of thiosugars, 7-(hydroxymethyl)thiepane-3,4,5-triols from D-(-)-quinic acid.

In this study, the optimized structures, relative Gibbs free energy, and Boltzman weighting factor of (3R,4R,5R,7S)-7-(hydroxymethyl)thiepane-3,4,5-triolconformers were obtained by using DFT/B3LYP/ 6-311++G(d,p) method. Among these conformers, we selected the TC2, TC5, TC6 to be the major contribution conformers because they exhibited a quite low total energy compared with other conformers. For the NMR calculation, the GIAO/DFT/B3LYP, GIAO/DFT/OPBE, GIAO/DFT/mPW1PW91 and GIAO/HF single point calculation with 6-311++G(d,p),6-311+G(2d.p),cc-pVDZ and cc-pVTZ basis set of (3R,4R,5R,7S)-7-(hydroxymethyl)thiepane-3,4,5-triol were conducted to generate their 13C NMR chemical shifts.TC2,TC5,TC6 calculation result was very closed correlation with experimental, it was generated lower MAE and RMS value. A good calculation method and basis set choice to evaluate the theoretical chemical shifts for these conformers is DFT/OPBE/6-311+G(2d.p), the MAE value is 1.9 ppm RMS value is 2.4 ppm.
