Our work shows how poly(ethylene glycol), differently functionalysed at two ends, can be easily and efficiently synthesised from commercial synthetic dihydroxy PEG 600. First, we linked the polymer onto functionalysed silica gel using one of its hydroxyl end. Then the second hydroxy group was modified, and finally, the desymmetrized PEG was cleaved from the solid support

Abstract
Our work shows how poly(ethylene glycol), differently functionalysed at two ends, can be easily and efficiently synthesised from commercial synthetic dihydroxy PEG 600. First, we linked the polymer onto functionalysed silica gel using one of its hydroxyl end. Then the second hydroxy group was modified, and finally, the desymmetrized PEG was cleaved from the solid support
