    • Typical procedure for the nucleophilic aromatic substitution cyclization is described in the fallowings: A solution of 6-(4-fluorobenzoyl)-6′- hydroxy-2,2′-dimethoxy-1,1′-binaphthyl (6, 0.2mmol) in 20 mL of DMF was added K2CO3 (0.3 mmol) and stirred in refluxing for 24 h. The mixture was poured into water (40 mL) and extracted with EtOAc. The organic layer was washed with brine and dried over MgSO4. After removal of the solvent in vacuo, the reaction mixture was separated by PTLC (CHCl3) to afford dimer 7 (40, and timer 8 6
    • 3) to afford dimer 7 (40%) and timer 8 (6%).
