Scavenging of Fluorinated N,N‘-Dialkylureas by Hydrogen Binding: A Novel Separation Method for Fluorous Synthesis
摘要:
[GRAPHICS]A dramatic solubility increase in fluorous solvents is observed for N,N ' -di(polyfluoroalkyl)ureas when hydrogen binding complexes are formed with commercially available perfluoroalkanoic acid scavengers. As a case example, analytically pure peptides and esters are obtained using this novel separation method.

The synthesis of new fluorinated non-ionic surfactantsderivedfrom α-lactose, the N-[2- (F-alkyl)ethyl]-lactosylamines (3) and -lactobionamides (4), is described. These derivatives are readily prepared in good yield in an aza-Wittig reaction from: (i) 2-(F-alkyl)ethyl azides which are readily obtained from the corresponding 2-(F-alkyl)ethyl iodides; and (ii) α lactose (for compounds 3) and lactobionic

We have focused on the C5-modification of 2'-deoxyuridine with substituted heterocycles for bioactivity, such as antiviral or anticancer activity. Herein, we report a novel class of nucleoside analogues with perfluoroalkyltriazole moiety as an anticancer drug candidate. (C) 2010 Elsevier Ltd. All rights reserved.

Glucosamine- and galactosamine- based monosaccharides with highly fluorinated motifs
Synthesis of modified monosaccharides, derivatives of glucose and galactose, having a highly fluorinated chain, as a library of synthetic buildingblocks for hyaluronicacid (HA) modified subunits has been developed. “Click” chemistry has been employed as a strategy for the synthesis of these molecules. 1,2,3-triazole ring derivatives were obtained with good to excellent yields.
