该中间体在本合成路线中的序号：(XI)Intermediate (VII) is methylated with dimethylsulfate and KOH in refluxing aqueous dioxane affording apogossypol hexamethyl ether (VIII) . The cleavage of the methoxy groups with BBr3 and aqueous NaOH yields apogossypol (IX), which by reaction with N,N'-diphenylformamidine (X) affords gossypol bis(N-phenylimine) (XI), which is finally hydrolyzed.
