Metathesis approach to the synthesis of polyheterocyclic structures from oxanorbornenes.
[reaction: see text] The synthesis of stereochemically defined tri- and penta-heterocyclic ring systems 9 and 28, respectively, via the metathesis reaction of substituted oxanorbornanes derived from 3 is described.
