## Abstract Die Synthese und die Zuordnung sรคmtlicher Diastereomeren **2a โe** von 2,3,11,12โTetraphenyl[18]kroneโ6 werden beschrieben. Die Identifizierung des __transโantiโtrans__โIsomeren **2d** erfolgt durch NMRโspektroskopisch gezeigte chirale Wechselwirkung von optisch aktiven 1โPhenylethylโam
octadecanes have been preparedin single step reactions from the readily-available chiralprecursors, (RR)-and (5%).hydrobenzoins, followed by bulk isolations of the pure Id-crown-6 derivatives via their I.9 crystalline complexes with potassium nitrate (for the Uiphenyl derivative) or calcium nitrate
