Trifluoromethylation of 1-aryl-3,3-diisopropyltriazenes
Hafner, Andreas,Braese, Stefan
supporting information, p. 996 - 1000 (2013/05/08)
A new method for the trifluoromethylation of functionalized aromatic diisopropyltriazenes is described. In a facile two-step, one-pot synthesis, various functionalized trifluoromethyl-substituted arenes are accessible in mostly good yields by using methyl iodide as iodination agent and the trifluoromethylation system (trifluoromethyl)trimethylsilane/potassium fluoride/copper iodide. This concept could be expanded to perfluoroethylation as well as ethoxycarbonyldifluoromethylation reactions. Copyright
Highly selective trifluoromethylation of 1,3-disubstituted arenes through iridium-catalyzed arene borylation

supporting information; experimental part, p. 540 - 543 (2012/03/11)
The old one two: A sequential iridium-catalyzed borylation and copper-catalyzed trifluoromethylation of arenes is described (see scheme; Pin=pinacol). The reaction is conducted under mild reaction conditions and tolerates a variety of functional groups. T
A general strategy for the perfluoroalkylation of arenes and arylbromides by using arylboronate esters and [(phen)CuRF]
Litvinas, Nichole D.,Fier, Patrick S.,Hartwig, John F.
, p. 536 - 539 (2012/02/16)
A versatile method for the synthesis of aryl perfluoroalkanes from arenes and aryl bromides is described. Substituted arenes or aryl bromides are converted in situ to an aryl boronate ester that readily undergoes perfluoroalkylation in air with [(phen)CuRF]. A broad range of aryl bromide substrates were perfluoroalkylated in good yield for the first time. [(phen)CuCF3] is now commercially available and has been prepared on 20g scale. Copyright
1,3,5-SUBSTITUTED PHENYL DERIVATIVE COMPOUNDS USEFUL AS BETA-SECRETASE INHIBITORS FOR THE TREATMENT OF ALZHEIMER'S DISEASE
-
Page/Page column 101, (2010/02/14)
The present invention is directed to 1,3,5-phenyl substituted derivative compounds which are inhibitors of the beta-secretase enzyme and that are useful in the treatment of diseases in which the beta-secretase enzyme is involved, such as Alzheimer's disease. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the treatment of such diseases in which the beta-secretase enzyme is involved.
