| Abstract | The enantiomers of the chiral 2,3-diphenyl- and 2,3,11,12-tetraphenyl-1,4,7,10,13,16-hexaoxacyclooctadecanes have been prepared in single step reactions from the readily-available chiral precursors, (RR)- and (SS)-hydrobenzoins, followed by bulk isolations of the pure 18-crown-6 derivatives via their 1:1 crystalline complexes with potassium nitrate (for the diphenyl derivative) or calcium nitrate (for the tetraphenyl derivative), obtained directly from the worked-up crude reaction mixtures: X-ray crystal structures characterise the uncomplexed (RRRR)-tetraphenyl-18-crown-6 and the 1:1 complex formed between its (SSSS)-enantiomer and calcium nitrate. © 1989. |
