Asymmetric Synthesis and Chiroptical Properties of Enantiopure Helical Ferrocenes
An enantiopure helical ferrocene (Rp)-5 with five ortho-condensed aromatic rings was synthesized using a PtCl2catalyzed cycloisomerization of planar-chiral 2-ethynyl-1-(4-phenanthrenyl)ferrocene (Rp)-6f, prepared in 3 steps from known enantiopure sulfinyl ferrocenyl boronic acid (SS,Sp)-7, as the so...

| Sumario: | An enantiopure helical ferrocene (Rp)-5 with five ortho-condensed aromatic rings was synthesized using a PtCl2catalyzed cycloisomerization of planar-chiral 2-ethynyl-1-(4-phenanthrenyl)ferrocene (Rp)-6f, prepared in 3 steps from known enantiopure sulfinyl ferrocenyl boronic acid (SS,Sp)-7, as the source of planar chirality. This pentacyclic helical ferrocene showed a very high optical rotation value and strong CD signals |
