Abstract:
The syntheses of the racemic amino alcohol rac-N(CH2CMe2OH)(CMe2CH2OH)(CH2CHMeOH) (LH3, 2) and its representative N(CH2CMe2OH)(CMe2CH2OH)(CH2C(R)HMeOH) (LH3, 3) with the stereogenic carbon center being R-configured are reported. Also reported are the stannatranes LSnOt-Bu (4) LSnOt-Bu (6) and germatranes LGeOEt (5) and LGeOEt (7) as well as the trinuclear tin oxocluster [(μ3-O)(μ3-O-t-Bu){SnL}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.

A consequence of chirality is the need for enantiomeric resolution. While this is theoretically possible for all...
Radicals: Electronic Structure and Geometry
Accordingly, the structure of a trivalent radical lies between the geometries of carbocations and carbanions. An sp2-hybridized carbocation is trigonal planar, while an sp3-hybridized carbanion is trigonal pyramidal. Here, the difference in geometry is...

Chirality
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...
