Syntheses and Structures of Binaphthyl-bridged Schiff Bases


  The reaction of dinaphthofuran with lithium in anhydrous diethyl ether led to a solution of the corresponding C,O-dilithiated intermediate which, upon treatment with DMF at ?78 oC, afforded, after hydrolysis, 2 -hydroxy-1,1 -binaphthyl-2-carbaldehyde in a good yield. Then binaphthyl-bridged Schiff bases were prepared by the condensation of 2 -hydroxy-1,1 -binaphthyl-2-carbaldehyde with the corresponding aromatic amines.……
