## Abstract **Summary:** Novel 2,3‐__O__‐hydroxyethyl‐ and 2,3‐__O__‐hydroxypropyl cellulose products were synthesized by heterogeneous etherification of 6‐__O__‐(4‐monomethoxytrityl) cellulose (MMTC). Due to the very hydrophobic character of MMTC, the reaction was successful in the presence of ani

## Abstract Regioselectively ethylated celluloses, 2‐__O__‐ (1), 3‐__O__‐ (2), and 6‐__O__‐ethyl‐ (3) celluloses were synthesized via ring‐opening polymerization of glucopyranose orthopivalate derivatives. The number‐average degrees of polymerization (__DP__~n~s) of compounds 1 and 2 were calculate
## Abstract End‐functionalized (1→6)‐2,5‐anhydro‐3,4‐di‐__O__‐methyl‐D‐glucitols (3a–c) were synthesized by the anionic cyclopolymerization of 1,2:5,6‐dianhydro‐3,4‐di‐__O__‐methyl‐D‐mannitol (1), followed by treatment with a terminating agent such as 4‐vinylbenzyl (2a), oxetanyl (2b), and methacry
