摘要

Abstract The use of Boc as a nucleobase-protecting group in the synthesis of sugar-modified thymidine analogs is reported. Boc was easily inserted at N (3) by a simple and high- yielding reaction and found to be stable to standard treatments for the removal of Ac and t BuMe 2 Si (TBDMS) groups, as well as to ZnBr 2-mediated 4, 4′-dimethoxytrityl (DMTr) deprotection. Boc Protection proved to be completely resistant to the strong basic ...
