Cyclofunctionalization oxygen nucleophiles

Cyclofunctionalization reactions involving oxygen nucleophiles have been studied more extensively than reactions involving any other heteroatom. Examples of functional groups used as oxygen nucleophiles are shown in Figure 1. [Pg.367]

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]
