Development of an Efficient Stereoretentive Para‐Claisen‐Cope Rearrangement

ChemistryEurope
A stereoretentive para‐Claisen‐Cope rearrangement of chiral aryl‐allyl ethers is reported, achieving near‐perfect chirality transfer thereby furnishing products with exceptional enantiomeric excess (up to > 98% ee) as single regioisomers.
