The synthesis of three new chiral vanadatranes by reaction of oxovanadium(V) alcoholates with triethanolamine derivatives obtained from the terpenes (-)-beta-pinene, (-)-limonene, and (-)-menthone is reported. Their structure is elucidated by NMR spectroscopy (H-1, C-13, N-15, O-17, V-51). (C) 2002 Elsevier Science B.V. All rights reserved,
