Abstract

A convenient and efficient synthetic route to differentially functionalized polyethylene glycols (PEGs) starting from cheap commercially available materials is reported. Selectively protected triethylene glycol or tetraethylene glycol have been reacted with a second PEG bearing both a protecting group and a leaving group.
