合成路线:The Friedel Crafts condensation of fumaryl chloride (I) with bromobenzene (II) gives 1,2-bis(4-bromobenzoyl)ethylene (III),which is reduced with Zn and Ac-OH to yield 1,4-bis(4-bromophenyl)butane-1,4-dione (IV).The cyclization of (IV) in refluxing Ac2O affords 2,5-bis(4-bromophenyl)furan (V),which is treated with CNCu in refluxing quinoline to provide 2,5-bis(4-cyanophenyl)furan (VI).The reaction of (VI) with HCl in ethanol gives the bis imidate (VII),which is finally treated with O-methylhydroxylamine to yield the target bis O-methylamidooxime.

合成路线:The reaction of furan (I) with BuLi and Bu3Sn-Cl gives the bis tributyltin derivative (II),which is condensed with 4-bromobenzonitrile (III) by means of Pd(PPh3)4 in dioxane to yield 4,4'-(furan-2,5-diyl)-bis(benzonitrile) (IV).The reaction of (IV) with HCl and ethanol affords 4,4'-(furan-2,5-diyl)bis(ethyl benzimidate) (V),which is finally treated with O-methylhydroxylamine in ethanol to provide the target bis-O-methyl benzamidoxime.
