✦ Synopsis

Cis-fused chiml bicyclic acetals are readily prepared from glycak in a two-step procedure via the tri-n-butylstannane-mediated cyclization of simple W-unsaturated glycosides of 2-bromo-2-deory-glycopymnosides.

Since a large and growing number of natural products have been shown to contain fused cyclic acetals, such as furo [2,3-b]furans, as part structures [1] and since many of them have a variety of activities (e.g., antitumor, antimicrobial, and insect antifeedant), interest has rapidly grown and result
