Abstract
Azaspirononanes of formula I and their synthesis ##STR1## are disclosed. The compounds are useful as templates for constructing synthetic receptors and as intermediates in the synthesis of enzyme inhibitors. They are prepared by an intramolecular ylide cycloaddition of a 6-hydrazone of 2,10-undecadienoic acid ester.
