  gem-Dimethyl 4-Pentenyl Glycosides: Novel Glycosylating Agents and Anomeric Protecting Groups

  摘要：

  Two classes of gem-dimethyl 4-n-pentenyl glycosides (i.e., C2-series and C3-series) have been prepared and studied in both the glycosylation and hydrolysis manifolds utilizing NBS as the sole stoichiometric activator. These novel glycosylating agents, which are analogues of Fraser-Reid's 4-n-penterryl glycosyl donors, show increased reactivity in side-by-side studies by virtue of the gem-dimethyl effect.
