Synthesis and Chiral Resolution of <i>C</i>₃‐Symmetric Tribenzotriquinacenes

Abstract

The synthesis and chiral resolution of a C 3 ‐symmetric triaminotribenzotriquinacene is reported. Both enantiomers were obtained in good yields and excellent enantiomeric purity by selective precipitation of their monodibenzoyltartrate salts. Conversion of the enantiopure ( M )‐triaminotribenzotriquinacene into a C 3 ‐symmetric triiodide highlights the usefulness of this compound as a starting point for the preparation of other enantiopure C 3 ‐symmetric tribenzotriquinacene derivatives, which may find application as building blocks for the preparation of chiral molecules in the nanosize regime.
