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.
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.

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.
