Organocatalytic diastereo- and atroposelective construction of eight-membered bridged (hetero)biaryls via asymmetric intramolecular [3+2] cycloaddition

An unprecedented and straightforward route for the asymmetric construction of privileged atroposelective bridged (hetero)biaryl eight-membered scaffolds has been accomplished through chiral phosphoric acid catalyzed asymmetric intramolecular [3+2] cycloaddition of innovative...
