WebFeb 15, 2024 · Mechanically chiral molecules are chiral due to interlocking of achiral covalent subcomponents. They are under investigation in catalysis, materials chemistry, and sensing, but their synthesis remains challenging. We report a simple chiral macrocycle that allows the synthesis of both rotaxanes and catenanes in excellent diastereopurity. … WebMay 19, 2011 · The controlled formation of lanthanide(III) dinuclear μ-hydroxo-bridged [Ln2L2(μ-OH)2X2]n+ complexes (where X = H2O, NO3–, or Cl–) of the enantiopure chiral macrocycle L is reported. The 1H and 13C NMR resonances of these complexes have been assigned on the basis of COSY, NOESY, TOCSY, and HMQC spectra. The … WebIn fact, the chiral auxiliary will allow us to control the synthesis of many enantiomerically pure isomers in natural product synthesis.
