| Summary: | The naturally abundant, enantiomerically pure cyclitol quinic acid has been converted into a synthetically useful enone in nearly quantitative yield using the operationally straightforward and reproducible protocols reported herein. The latter compound, which was obtained in multigram quantities, engages in a diastereoselective 1,2-addition reaction with a hydrazone-based nucleophile. Furthermore, a readily derived α-iodoenone participates in both cross-coupling and α,β-annulation reactions. The results reported here emphasize that the now practically accessible cyclohexenones are useful, enantiomerically pure building blocks for organic synthesis.
