Neighboring Lithium-Assisted [1,2]-Wittig Rearrangement: Practical Access to Diarylmethanol-Based 1,4-Diols and Optically Active BINOL Derivatives with Axial and sp3-Central Chirality
synthetically useful diarylmethanol‐based 1,4‐diols and enantiomericallypure BINOL‐derived diols with axial and sp3‐central chirality has been developed through neighboring lithium‐promoted [1,2]‐Wittig rearrangement. The chirality transfer process shows a broad substrate scope in terms of the aromatic ether substituent, which allows access to a broad of range of chiral 1,1′‐binaphthalene‐2‐α‐arylmethanol‐2′‐ols
