Radical Cyclization of Sugar-Derived β-(Alkynyloxy)acrylates: Synthesis of Novel Fused Ethers
摘要:
Tributyltin radical mediated cyclization of carbohydrate-derived beta-(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 trans-fused tricyclic tetrahydropyran.
