摘要：

Two twisted: Optically active double helices were synthesized through a twist-sense bias induced by a chiral phosphine ligand on one of the complementary metallostrands followed by a ligand-exchange reaction with an achiral bidentate ligand, which replaces the chiral ligand, to bridge the two strands. Furthermore, the double helices can efficiently catalyze asymmetric cyclopropanation. (Figure Presented). © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
