合成路线1
该中间体在本合成路线中的序号:(I)Irisquinone was originally isolated from some Iris species. The total synthesis of this compound has been reported by several procedures. 10-cis-Heptadecenoic acid (I) was converted to the Weinreb amide (II) via the corresponding acid chloride. Regiospecific ortho-lithiation of veratrole (III), followed by acylation with the N-methoxy amide (II), afforded ketone (IV). Selective mono-demethylation of (IV) with boron trichloride yielded phenol (V). Clemmensen reduction of the keto group of (V) employing zinc amalgam furnished 2-(cis-10-heptadecenyl)-6-methoxyphenol (VI). This was finally oxidized to the target quinone by means of oxygen gas in the presence of salcomine.
