Armed-disarmed concept chemoselectivity

Scheme 5.8 Armed/disarmed concept for chemoselective coupling of two w-pentenyl glycosides (NPGs). A 2-0-alkylated (armed) NPG 29 is much more readily activated than is a 2-0-acylated (disarmed) NPG 30.62...

The concept of armed/disarmed glycosyl donors was subsequently extended by other groups to thioglycosides21 and selenoglycosides.64 A similar strategy has been used by Friesen and Danishefsky to achieve chemoselectivity in electrophilic addition to glycal double bonds.65... [Pg.109]
