    • Stable existence of the chiral plane in rac [6] and [7]metacyclophanes 3 (n = 3,4) at room temperature was verified by HPLC analysis employing the Shimadzu LC-6A instrument equipped with an SPD-6A UV detector as follows: Compound 3 (n = 3): chiral column, Daicel A(S)MBC, 4.6 mm i.d. X 25 cm; eluent, i-PrOH-hexane (1 : 40); flow rate, 1.0 rnL/min; detection, UV 254 nm; retention time of the racemate, 20.1 min and 22.6 min. Compound 3 (n = 4) : chiral column, Daicel CHIRALCELL OD, 4.6 mm i.d. X 25 cm; eluent, i-PrOH-hexane (1: 40) ; flow rate, 0.3 mL/min; detection, UV 254 nm; retention time of the racemate, 9.5 min and 10.8 min.
