    (Chemical Equation Presented) Twisted ethers: Introduction of a bulky alkylsulfinyl substituent ortho to the C-O axis of a diaryl ether imposes a powerful conformational preference (see scheme). The preference persists upon oxidation of the sulfoxide to a sulfone, leading to dynamic thermodynamic resolution of the atropisomeric ether. This is the first enantioselective synthesis of an atropisomeric diaryl ether not forming part of a macrocyclic ring. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
