摘要：

The combination of planar chirality and helicity gives rise to the novel stereochemical properties of the metallocene 1, which can be synthesized from a disubstituted cyclopentadiene derivative with a donor functionalized side chain. Cleavage of either one or both metal‐chelate arms transforms 1 into single diastereomers of 2 and 3, respectively, with complete retention of configuration of the chiral planes. (Figure Presented.)
