The stereospecific synthesis of (2R,3R,8R,9R,14R,15R)-2,3,8,9,14,15-hexaphenyl-1,4,7,10,13,16- hexaoxacyclooctadedecane [(R,R,R,R,R,R)-12] from (R,R)-hydrobenzoin [(R,R)-1] is reported. The ability of (R,R,R,R,R,R)-12 to act as a chiral solid-liquid phase
SYNTHESIS OF (-)-2S,3S,11S,12R-2,3,11,12-TETRAPHENYLCROWN-6

, p. 1193 - 1198 (2007/10/02)
The synthesis of (-) 2S,3S,11S,12R-2,3,11,12-tetraphenyl-crown-6 from (-)-1S,2S-hydrobenzoin and meso-hydrobenzoin is described.Chemical shifts and vicinal coupling constants of the benzylic protons in the 2S,3S and 11S,12R substructures in the free ligands and in complexes with KSCN and 1-phenylethylammonium bromides and a brief discussion of the related conformational changes are also presented.A detailed procedure for the resolution of racemic hydrobenzoin is given.
Synthesis and Ligand Properties of the 2,3,11,12-Tetraphenylcrown-6 Diastereomers

, p. 1774 - 1784 (2007/10/02)
The synthesis and the assignment of the complete set of diastereomers 2a-e of 2,3,11,12-tetraphenylcrown-6 are described.The trans-anti-trans isomer 2d is identified by chiral interaction of optically active 1-phenylethylammonium hydrobromides with the racemic crown ether shown by NMR spectroscopy.Complex association constants of the new crown ethers with sodium, potassium, and ammonium picrates are discussed in terms of the geometry of the diastereomers.
