Thesis advisor: Jia Niu / Thesis advisor: Jim Morken / Polysaccharides make up one of the largest classes of nature’s macromolecules. However, they are severely understudied relative to other biomolecules such as proteins and DNA sequences. This is because discrete polysaccharides are difficult to isolate from nature or synthesize in laboratories in large enough quantities for thorough research. Polymerization is an efficient route to polysaccharides, yet has historically suffered from harsh conditions and lack of control. Herein, we investigate recent developments in the field of living polymerization as strategies towards synthesis of precision polysaccharides from 1,2- anhydrosugars. We specifically focus on cationic ring opening polymerization (ROP) and reversible addition-fragmentation chain transfer (RAFT) ROP polymerization of 1,2-O-Bn-3,4,6-anhydromannose and 1,2-O-Bn-3,4,6-anhydroglucose. Our research screens various catalyst/initiating systems. Our findings demonstrate that cationic ROP and RAFT polymerization are unsuccessful in the living ROP of 1,2-anhydrosugars. / Thesis (MS) — Boston College, 2023. / Submitted to: Boston College.
