Heteroatomic coupling oxygen nucleophiles

Alkyl ethers can act as nucleophiles in cyclofunctionalization reactions,17 and recently acetal oxygens have been shown to be excellent nucleophiles for participation in heteroatom cyclizations (Scheme 9). This reaction has been used as a nonhydrolytic procedure for unraveling complex acetals (conversion of 9 to 10),180 for specific liberation of an anomeric center (conversion of 11 to 12),181a for preparation of glycosyl bromides18115 and for saccharide coupling (reaction of 13 and 14 to give 15).182... [Pg.391]
