Extending Chirality in Group XIV Metallatranes.

The syntheses of the racemic amino alcohol -N(CHCMeOH)(CMeCHOH)(CHCHMeOH) (H, ) and its representative N(CHCMeOH)(CMeCHOH)(CHC()HMeOH) (H, ) with the stereogenic carbon center being -configured are reported. Also reported are the stannatranes SnO-Bu () SnO-Bu () and germatranes GeOEt () and GeOEt () as well as the trinuclear tin oxocluster [(μ-O)(μ-O--Bu){Sn}] (). NMR and IR spectroscopy, electrospray ionization mass spectrometry (ESI MS), and single crystal X-ray diffraction analysis characterize these compounds.
