摘要：

(Figure Presented) Giving lanthanides a new twist: The chiral nonaaza macrocycle L wraps tightly around lanthanide(III) ions in a helical fashion (see picture). The all-R enantiomer of the macrocycle, LRRRRRR, forms kinetically controlled complexation products of M helicity (100% de), which undergo inversion to the P diastereomer (90% de). Both products have been isolated in enantiopure form and structurally characterized. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
