Alkyl- and aryl-substituted 4-azuleneethanamines, non-benzenoid analogs of biological active amines, were synthesized by the reaction of sodium guaiazulenide with methyleneiminium salt. These compounds were characterized by spectral data.

Selective hydride (LiH) addition via an unprecedented catalytic olefin hydrolithiation and protonabstraction at guaiazulene is documented in full detail, including isolation of analytically and isomerically pure samples, their NMR and XRD structural characterization. Both cyclopentadienyl type carbanions will allow to substitute petrochemical-based by renewable resources-based organometallic chemistry
