The interaction of 2-nitrocinnamates with silicon reagents Me(3)SiR(f) (R(f) = CF(3), C(2)F(5), and C(6)F(5)) promoted either by sodium acetate in DMF or by tetrabutylammonium acetate in dichloromethane has been describe...
O-Dodecyl-N,N'-diisopropylisourea and O-tridecafluorooctyl-N,N'-diisopropylisourea were synthesized by reaction of hydrogenated or fluorinated alcohols onto diisopropylcarbodiimide in quasi-quantitative yields. Adding va...
In situ-generated unsubstituted, "parent" azomethine and thiocarbonyl ylides are used to prepare a large variety of 3-aryl- and alkyl-substituted, 4-pentafluorosulfanylpyrroles and 3-aryl-substituted, 4-pentafluorosulfan...
An effecient synthetic method for fluorinated tridentate beta-aminoenones and tetradentate bis(beta-aminoenones) via amination of fluorinated 1,3-diketones with o-phenylenediamine in the presence of trialkyl borates was ...
A catalyst free cycloaddition reaction of 3-oxo-1,2-pyrazolidinium ylides with beta-trifluoroacetyl vinyl ethyl ether is reported, which proceeded smoothly at ambient temperature and afford the bicyclic pyrazolidinone pr...
A L-proline catalyzed condensation-cyclization tandem process is reported, which affords the potentially pharmaceutic coumarin derivatives. The mild conditions, simplicity of the purification process and satisfactory yie...
The synthesis of fluorous (highly fluorinated) 3,4-dihydro-2(1H)-pyridone-5-carboxylate cationic amphiphiles have been described, where the dihydropyridone serves as a spacer and either a pyridinium bromide or a tripheny...
The present article describes the synthesis of new fluorinated 10H-phenothiazines by Smiles rearrangement. The reaction of these synthesized phenothiazines with sugar (beta-D-ribofuranose 1-acetate-2,3,5-tribenzoate) aff...
Reaction of perfluoroalkyl groups with carbon-carbon unsaturated compounds using indium in water proceeded smoothly to provide the addition products in high yields. (C) 2011 Elsevier B.V. All rights reserved.
