title: Preparation of both antipodes of enantiopure inherently chiral calix[4]crowns.
abstract: Both antipodes of enantiopure inherently chiral calix[4]crown derivatives were successfully obtained through separation of their BINOL diastereomeric derivatives of corresponding racemates using preparative TLC instead of conventional HPLC methods. Such a result provides a basis for future study of chiral recognition and asymmetric catalysis with inherently chiral calixrene derivatives.
