摘要: Abstract New steroid dimer, ethylene bridged bis-carbamate ( 3) was synthesized from cholic acid in few steps. Complexes of 3 with lanthanum(III) and calcium(II) nitrates were prepared reaction appropriate metal salts. They characterized by spectral data (Infrared (IR), ultraviolet-visible (UV/Vis), nuclear magnetic resonance (NMR) spectroscopy fast-atom bombardment (FAB), electrospray (ESI) matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS)) elemental analysis. The similarity complexing behavior steroidal dimer toward calcium lanthanum ions observed.
