Abstract
A novel and efficient methodology for the stereocontrolled synthesis of spirocyclic oxa-bridged cyclooctanoids having multiple spiro centers is described. The cycloaddition reaction, which affords spirocyclic cyclooctanoids is highly sterospecific and has been supported by theoretical calculations.
Key words
pentafulvenes - oxidopyrylium betaines - oxa-bridged spirocycles - macromolecules
