A new synthetic route to chiral, multiply functionalized cyclopentane rings

The tribyltin hydride mediated free radical cyclization of sugar derivatives 4-6 gives the annulated furanose 9-11 in good yield and high diastereoselectivity. This protocol is a new synthetic route for the preparation of complex cyclopentanoid molecules.
