Abstract: ConspectusSince Ludwig Claisen's discovery of the sigmatropic rearrangement of allyl aryl ethers in 1912, aromatic Claisen rearrangement has continuously attracted the attention of both experimental and theoretical chemists. Over more than a century of growth,… read more here.

Abstract: The first catalytic enantioselective aromatic Claisen rearrangement of allyl 2-naphthyl ethers using 5–10 mol% of π–copper(ii) complexes is reported. A Cu(OTf)2 complex with an l-α-homoalanine amide ligand gave (S)-products in up to 92% ee. Conversely,… read more here.
