## Abstract Endβfunctionalized (1β6)β2,5βanhydroβ3,4βdiβ__O__βmethylβDβglucitols (3aβc) were synthesized by the anionic cyclopolymerization of 1,2:5,6βdianhydroβ3,4βdiβ__O__βmethylβDβmannitol (1), followed by treatment with a terminating agent such as 4βvinylbenzyl (2a), oxetanyl (2b), and methacry
The cyclopolymerization of 3,4-di-O-allyl-1,2 : 5,6-dianhydro-D-mannitol ( 1) was carried out using BF 3 rOEt 2 and t-BuOK. The polymer obtained by the polymerization with BF 3 rOEt 2 mainly consisted of (1r6)-bonded 3,4-di-O-allyl-2,5-anhydro-Dglucitol as the five-membered constitutional repeating
