Stereoselective Construction of Tertiary Homoallyl Alcohols and Ethers by Nucleophilic Substitution at Quaternary Carbon Stereocenters

open access: yesAngewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023
A highly efficient stereoinvertive nucleophilic substitution at the quaternary carbon stereocenter of cyclopropyl carbinol derivatives using water, alcohols and phenols as nucleophiles is reported. A variety of highly sterically hindered tertiary alkyl ethers and alcohols with adjacent tertiary carbon stereocenters are obtained in good yields with ...
