Abstract
  • A modular synthetic approach was developed toaccess triamines with varying tether lengths from commercially available aminoalkanols. Initial N-alkylation viareductive amination with anthracene-9-carbaldehyde provided the secondary amines in good yield. Subsequentditosylation with excess TsCl yielded the respective bis-N,O-tosylates. The tosylates were reacted with excess putrescineto give the final triamines. X-ray crystallography revealedthat the polyamine tail is preferentially oriented over theshielding cone of the anthracene ring.
