Abstract
Bis-N-hydroxysuccinimide ester of 1,10-decanediol bis-succinate (Ia) reacts with hydroxyl groups bearing polymers (Spheron, cellulose, Sephacryl) affording activated carboxyl group containing derivatives IIa. Analogous 4-nitrophenyl group bearing Spheron derivative IIb was prepared starting from bis-4-nitrophenyl ester of 1,10-decanediol bis-succinate (Ib). 3'-O-(4,4'-Dimethoxytriphenylmethyl)-2'-deoxythymidine 5'-(6-amino-1-hexyl)-phosphate (V) was developed as reagent to determine the extent of activated carboxyl groups. Attachment ranging from 3.1-7.3 μmol/g was achieved.
