The syntheses of the novel.amino alcohols NH(CH2CMe2OH)(2)(CMe2CH2OH) (1) and N-(CH2CMe2OH)(CMe2CH2OH)(CH2CH2OH) (2) as well as the stannatranes N(CH2CMe2OH)(CMe2CH2OH)-(CH2CH2OH)-SnX (3, X = Ot-Bu), N(CH2CMe2O)(3)SnOC-(O)C9H13O2, 4, and germatranes N(CH2CMe2O)-(CMe2CH2O)(CH2CH2O)GeX (5, X = OEt; 6, X = Br) are reported. The-compounds were characterized by H-1, C-13, (1-6), Sn-119 (3, 4), and N-15 (2, 3, 5) NMR and:JR spectrokopy, electrospray ionization mass spectrometry, and single crystal X-ray diffraction analysis. Graphset, analyses were performed for, compounds 1 and 2. Detailed NMR spectroscopic Studies including variable temperature H-1 (3, 5, 6) and Sn-119 (3, 4) DOSY experiments reveal the stannatrane 3 being involved in a monomer dimer equilibrium. Both the stannatranes 3 and 4 as well as the germatranes 5 and 6 show Lambda = Delta isomerization of the atrane cages in solution.
