Résumé: A straightforward slippage strategy has been used for the synthesis of three [2]rotaxane building blocks that all contain anammonium template for the dibenzo-24-crown-8 macrocycle and an N-hydroxysuccinimide end. The kinetic rate of the slipping-on process proved to be highly dependent on both the length and flexibility of the thread.

Synthesis of 3-trifluoromethyl- and 3-perfluoroalkyl-substituted 3-aryloxy- and 3-heteroaryloxypropenoic acids and of the cyclization products, 2-trifluoromethyl- and 2-perfluoroalkyl-4H-chromen-4-ones

(Article) Publié:
Synthesis, vol. p.3542-3552 (2007)
Résumé: We describe a novel and simple method for the regiospecific synthesis of functionalized trifluoromethyl- and perfluoro-alkyl-containing 4H-chromen-4- ones via the cyclization of substituted 3-aryloxy-3-perfluoroalkylpropenoic acids. The procedures give the final products in high yields, without any need for chromatographic purification, and no side products.

Novel synthesis, reactivity, and stereochemistry of substituted 3-trifluoromethyl- and 3-perfluoroalkyl-3-phenoxyprop-2-enal
Auteur(s): El Kharrat S., Laurent P., Blancou H.
(Article) Publié:
European Journal Of Organic Chemistry, vol. 71 p.6742-6752 (2006)
Résumé: Substituted 3-phenoxy-3-perfluoroalkylprop-2-enals 3a-s are synthesized in high yields starting from a gem-iodoacetoxy derivative 1 and phenoxides 2. Then efficient syntheses of push-pull derivatives 4, 5, 8a, b, and nonconjugated analogues 6 and 7 illustrate the synthetic potentialities of 3. Stereochemical studies of these perfluoroalkyl-containing trisubstituted olefinic derivatives 3-8b revealed that the (4)J(CF) coupling constant observed in the C-13 NMR spectra was crucial in the determination of their configurations and conformations in solution. The solvent polarity effect on the stereochemistry of push-pull compounds 3-5 and 8a, b was studied. Unusual significant medium polarity effect on the stereochemistry of imino enol ether derivative 4 was observed.
