Spiroketals via oxidative rearrangement of enol ethers
David L. Waller, Corey R. J. Stephenson and Peter Wipf
Oxidative rearrangement of cyclic enol ethers leads to
-alkoxyesters. In the presence of a neighboring spiroether, this approach provides a stereoselective access to spiroketals. A modified proposal for the biosynthesis of acutumine is presented.
