Vinuales, Ana I.,Serrano, Jose Luis,Gimenez, Raquel,Pinol, Milagros,Tomczyk, Jaroslaw,Stumpe, Joachim
, p. 3499 - 3512 (2011)
Cinnamate-containing dendrimers have been prepared by peripheral functionalization of the amine groups of a poly(propyleneimine) dendrimer with 4-methoxycinnamate- or 4-(N,N-dimethylamino)cinnamate-derived units and/or 4-cyanobiphenyl units in different p
CONTRAST AGENTS ENDOWED WITH HIGH RELAXIVITY

Page/Page column 93-94, (2008/06/13)
The present invention relates to a novel class of paramagnetic ion-based contrast agents of formula (I), wherein a chelating backbone moiety is highly functionalized by the presence of one or more polyhdroxylated chain, that show a pharmacokinetic profile analogous to that of the commonly used T1-general extravascular agents (NSA) but are further characterized by a higher relaxivity.
Synthesis of ω-(2-oxocyclododecyl)alkanoic acids by alkylation of cyclododecanone with ω-haloalkanoic esters under conditions of phase-transfer catalysis
Zakharkin, L. I.,Antonova, G. N.,Podvisotskaya, L. S.
, p. 2418 - 2419 (2007/10/03)
ω-(2-Oxocyclododecyl)alkanoic acids have been obtained by alkylation of cyclododecanone with alkyl 3-bromopropionate, 5-iodopentanoate, and 11-bromoundecanoate under conditions of phase transfer catalysis. - Key words: cyclododecanone, phase-transfer catalysis, alkylation, alkyl ω-haloalkanoates.
