The synthesis of a chiral hexaphenyl-18-crown-6 derivative

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 and Ligand Properties of the 2,3,11,12-Tetraphenylcrown-6 Diastereomers

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.
