Asymmetric [2,3]‐Wittig Rearrangement of Oxygenated Allyl Benzyl Ethers in the Presence of a Chiral di‐ t Bu‐bis(oxazoline) Ligand: A Novel Synthetic Approach to THF Lignans

We have accomplished highly enantioselective [2,3]‐Wittig rearrangements of functionalized allyl benzyl ethers in the presence of a chiral di‐ t Bu‐bis(oxazoline) ligand. In various oxygenated benzylic ethers, the reactions proceeded with excellent diastereo‐ and enantioselectivities, although the p...
