合成路线1
该中间体在本合成路线中的序号:(I)The reaction of 1-bromo-3,5-dimethyladamantane (I) with Li in ethyl ether gives the corresponding lithium derivative, which is treated with NH2-Cl (II) to afford the target 1-aminoadamantane.
合成路线2
该中间体在本合成路线中的序号:(I)1-Bromo-3,5-dimethyladamantane (I) is subjected to Ritter reaction with acetonitrile in the presence of H2SO4 to produce acetamide (II). This is further hydrolyzed to the aminoadamantane (III) employing NaOH in refluxing diethyleneglycol. Condensation of amine (III) with maleic anhydride (IV) leads to the maleamic acid (V), which is finally cyclized to the target maleimide upon heating in acetic anhydride in the presence of NaOAc.
