Radical cyclization of sugar-derived β-(alkynyloxy)acrylates: Synthesis of novel fused ethers

(equation presented) Tributyltin radical mediated cyclization of carbohydrate-derived β-(alkynyloxy)acrylates leading to highly functionalized cis-and trans-fused bicyclic ethers of various ring sizes is described. The efficacy of the radical cyclization is nicely illustrated in the iterative construction of a frans-fused tricyclic tetrahydropyran.
