The introduction of sulfur atoms into trifluoromethylated alkenyl sulfones and chlorides were studied using a reactive sulfur-graphite electrode in N,N-dimethylformamide. A substrate, 2-(4-biphenylyl)-4,4,4-trifluoro-3-phenylsulfonyl-2-butenenitrile (1a) afforded a coupling compound bridged with a nitrogen atom of isothiazole and 1,2-dithiolane skeleton (2). 1-(4-Biphenylyl)-3,3,3-trifluoro-2-phenylsulfonylpropene (1b) without a cyano group gave a complex oligomeric compound (3) without the elimination of the phenylsulfonyl group. 2- (4-Biphenylyl)-3-chloro-4,4,4-trifluoro-2 butenenitrile (1c) having a chloro group as a leaving group gave 2,4-di (4-biphenylyl)-2,4-dicyano-1,5-bis (trifluoromethyl)-3,6-dithiabicyclo[3.1.0]hexane (4) and 2-(4-biphenylyl)-4,4,4-trifluoro-2-butenenitrile (5). Methyl 2-(4- biphenylyl)-3-chloro-4,4,4-trifluoro-2-butenoate (1d) having an ester group in the place of a cyano group afforded di-[2-(4 biphenylyl)-2-methoxycarbonyl-1 trifluoromethylethyl] disulfide (6). The formation of such sulfur-containing organofluorine compounds except for the oligomeric compound 3 is characterized as the addition of polysulfide anion(s) produced by electroreduction of elemental sulfur. followed by the elimination of the phenylsulfonyl or the chloro group.

In this study, we have determined and compared the pharmacological profiles of ibotenic acid and its isothiazole analogue thioibotenic acid at native rat ionotropic glutamate (iGlu) receptors and at recombinant rat metabotropic glutamate (mGlu) receptors expressed in mammalian cell lines. Thioibotenic acid has a distinct pharmacological profile at group III mGlu receptors compared with the closely structurally related ibotenic acid; the former is a potent (low mum) agonist, whereas the latter is inactive. By comparing the conformational energy profiles of ibotenic and thioibotenic acid with the conformations preferred by the ligands upon docking to mGlu(1) and models of the other mGlu subtypes, we propose that unlike other subtypes, group III mGlu receptor binding sites require a ligand conformation at an energy level which is prohibitively expensive for ibotenic acid, but not for thioibotenic acid. These studies demonstrate how subtle differences in chemical structures can result in profound differences in pharmacological activity. (C) 2004 Elsevier B.V. All rights reserved.

In a document, author is Schalk, O., introduce the new discover, Formula: https://www.ambeed.com/products/209911-63-7.html.

The photoinduced dynamics of thiophene and 2,S-dimethylthiophene (2,5-DMT) were investigated upon excitation at 200 and 255 nm (2,5-DMT only) using time-resolved photoelectron spectroscopy and compared with results from ab initio coupled cluster calculations. For thiophene, depopulation of the initially excited B 2 (pi(3)pi(4)*) state to the lower-lying A(1) (pi(3)pi(4)*) state occurs within 25 +/- 20 fs, with a subsequent bifurcation into a ring-puckering channel and a ring-opening channel with lifetimes of 80 +/- 20 and 450 +/- 50 fs, respectively. For 2,5-DMT, the dynamics following excitation at 200 nm is described by a monoexponential decay with a time constant of 120 +/- 20 fs, while that following excitation at 255 nm is best fit by a biexponential decay with time constants of 115 +/- 20 fs and 15 +/- 3 ps, respectively. The fast signal observed after excitation of 2,5-DMT is assigned to the ring-opening channel, which is favored with respect to thiophene due to a lower excited-state barrier along the ring-opening coordinate and an increased inertia toward the ring-puckering channel. Coupled cluster calculations have been undertaken to compare the relaxation dynamics of thiophene to thiazole and isothiazole. For the latter two molecules, we find a strong gradient along the ring-opening coordinate in the Franck-Condon region of the initially populated pi pi* state and predict that ring-opening is the dominating relaxation channel after photoexcitation. We use the extracted information for a comparison of the thiophene dynamics with the light-induced processes observed in other five-membered heterocyclic molecules.

It was found that the reaction of 5-arylfurfurilamines with maleic anhydride leads to the formation of 6-aryl-3a,6-epoxyisoindole-7-carboxylic acids (the cyclic form), which in solution are in dynamic equilibrium with N-furfurylmaleinamides (the open form). During the esterification of these tautomeric mixtures with methanol in the presence of a catalytic amount of sulfuric acid, methyl esters of 5-aryl-7a-hydroxy-7-methoxy-3-oxo-2,3,3a,4,7,7a-hexahydro-1H-isoindole-4-carboxylic acids, unexpected cleavage products of the 3a,6-oxo bridge of the cyclic form, are formed diastereospecifically. The structure of the obtained products was confirmed by X-ray structural analysis.
