Scheme 1.

Scheme 1

Enzymatic and chemical polymerization approaches provide cellulose oligomers with a non-uniform distribution of MW. A) Cellulose oligomers can be synthesized using cellobiose fluoride 1 and cellulase. Other enzymes like cellodextrin phosphorylase (CDP) or cellobiose phosphorylase (CBP) use glucose (2a) or cellobiose (2b) primer respectively and glucose phosphate 3. B) Synthesis of cellulose by ROP from protected orthoester 4 promoted by Lewis acid (LA) or base (B).
