-
Page/Page column 18-19, (2010/11/25)
The invention relates to novel thiophene derivatives, their preparation and their use as pharmaceutically active compounds. Said compounds particularly act as immunosuppressive agents.
A rational utilization of high-throughput screening affords selective, orally bioavailable 1-benzyl-3-carboxyazetidine sphingosine-1-phosphate-1 receptor agonists
Hale, Jeffrey J.,Lynch, Christopher L.,Neway, William,Mills, Sander G.,Hajdu, Richard,Keohane, Carol Ann,Rosenbach, Mark J.,Milligan, James A.,Shei, Gan-Ju,Parent, Stephen A.,Chrebet, Gary,Bergstrom, James,Card, Deborah,Ferrer, Marc,Hodder, Peter,Strulovici, Berta,Rosen, Hugh,Mandala, Suzanne
, p. 6662 - 6665 (2007/10/03)
Moderately potent, selective S1P1 receptor agonists identified from high-throughput screening have been adapted into lipophilic tails for a class of orally bioavailable amino acid-based S1P1 agonists represented by 7. Many of the new
Preparation of pyrrole-2-carboxylates with electron-withdrawing groups at the 4-position
Uno, Hidemitsu,Tanaka, Masanori,Inoue, Takashi,Ono, Noboru
, p. 471 - 474 (2007/10/03)
Reaction of α-trifluoromethyl, α-cyano, and α-ethoxycarbonyl alkenyl sulfones with ethyl isocyanoacetate in the presence of a base gave 4- substituted pyrrole-2-carboxylates in moderate to good yields.
Synthesis of CF3-Substituted Quinolines from β-Chloro-β-trifluoromethyl-vinylaldehydes. I.
Greif, Dieter,Riedel, Dirk,Feindt, Andreas,Pulst, Manfred
, p. 34 - 37 (2007/10/02)
3-(Trifluoromethyl)-acroleines 2 have been synthesized through VILSMEIER's reaction from α-Trifluoromethylketones 1.The reaction of 2 with anilines and naphthylamines gives in good yields 2-trifluoromethylquinolines 4 and benzoquinolines 5.
Reactivity of β-(trifluoromethyl) acroleins towards primary alkyl (or aryl) amines: synthesis of trifluoromethyl)-1-aza-1,3-dienes and secondary (trifluoromethyl) allylamines
Selmi, A.,Gaied, M. M. El,Alvernhe, G.
, p. 1 - 8 (2007/10/02)
Vilsmeier's reaction on trifluoroketones leads to β-chloro-β(trifluoromethyl)acroleins.The addition of primary alkyl- or aryl-amines to these acroleins leads in all cases to the formation of stable (trifluoromethyl)-1-aza-1,3-dienes which can be transform
Synthesis of γγγ-trifluorocarbonyl compounds
Laurent,Lesniak
, p. 8091 - 8092 (2007/10/02)
γγγ-Trifluorocarbonyl compounds are easily obtained in a good yield by introduction of the 1,1,1-trifluoroethyl moiety (CF3-CH2-) on the α-methylene group of a ketone.
A new and efficient synthesis of trifluoroalkyl aldehydes or ketones from the same starting material
Laurent, Andre J.,Leniak, Stanislaw
, p. 3311 - 3314 (2007/10/02)
4,4,4-trifluoroacroleines 2 have been converted specifically by tributyl tin hydride to aldehyders 3 or ketones 4, according to the catalyst and conditions employed.
