摘　　要：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.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.
