✦ Synopsis


Chiral Allyl Cations in Cycloadditions to Furan: Synthesis of 2-(1'-Phenylethoxy)-8-oxabicyclo[3.2.1]oct-6-en-3-one in High Enantiomeric Purity.

-The new diastereo-and enantioselective route to the title compound (III) uses chiral 1-phenylethanol as both a convenient chiral auxiliary and a protecting group.
