Two syntheses of 1,1'-binaphthyl-2,2'-dicarboxylic acid (4) in good yields are presented via the oxidation of the 2'-methyl substituent of isopropyl 2'-methyl-1,1'-binaphthyl-2-carboxylate (8), which is readily obtainable by the reaction of 2-methyl-1-naphthyl Grignard reagent 7 with isopropyl 1-isopropoxy-2-naphthoate (6).
