Abstract
The syntheses of the racemic amino alcohol rac-N(CH2CMe2OH)(CMe2CH2OH)(CH2CHMeOH) (L22'1*H3, 2) and its representative N(CH2CMe2OH)(CMe2CH2OH)(CH2C(R)HMeOH) (L22'1RH3, 3) with the stereogenic carbon center being R-configured are reported. Also reported are the stannatranes L22'1*SnOt-Bu (4) L22'1RSnOt-Bu (6) and germatranes L22'1*GeOEt (5) and L22'1RGeOEt (7) as well as the trinuclear tin oxocluster [(μ3-O)(μ3-O-t-Bu){SnL22'1R}3] (8). NMR and IR spectroscopy, electrospray ionization mass spectrometry (ESI MS), and single crystal X-ray diffraction analysis characterize these compounds. Computational studies accompany the experimental work and help understand the diastereoselectivity observed in the course of the metallatrane syntheses.
