The first intramolecular 1,3-dipolar cycloaddition of an acyclic, chiral, polyfunetionalized 7-alkenyl tethered N-benzyl nitrone is reported. This is a new and efficient approach for the synthesis of chiral, densely functionalized cycloheptanes from carbohydrates.

Chiral, Densely Functionalized Cycloheptanes from Carbohydrates. Part 1. The Nitrone Route.
-The first example of an intramolecular 1,3-dipolar cycloaddition of a chiral, acyclic 7-alkenyl tethered N-benzyl nitrone (IV) is described that provides a new and efficient asymmetric access to chiral, densely functionalized cycloheptanes such as (V) from carbohydrates.
