This molecule has been synthesized in 13 steps from p-anisidine. The key steps in this synthesis include an intramolecular nucleophilic aromatic substitution mediated by potassium tert-butoxide, the selective reduction of a dinitro ester using catalytic hydrogenation, and the novel use of Fremy's salt to synthesize an [color=#f10b00]iminoquinone [/color]from an amino phenol. The synthesis of makaluvamine C has been achieved from p-anisidine in 13.1% overall yield. 满意答案 好评率：100% Makaluvamine C 是一种从海绵动物中提取的一种亚氨基吡咯醌。这种物质是从对茴香胺（p-anisidine.）开始经过13步合成而来，合成的关键不周包括：叔丁醇钾盐介导的芳香亲和取代、利用催化氢化进行的二硝基酯的选择性还原，还有利用Fremy盐从氨基苯酚合成[color=#f10b00]亚氨基醌[/color]。该合成路径的收率为13.1%。 = = = = = = [size=3][font=Times New Roman][b]You may keep the above website addresses (especially [/b][/font][/size][url=http://dict.cn/][color=#0000ff][size=3][font=Times New Roman][b]http://dict.cn[/b][/font][/size][/color][/url][size=3][font=Times New Roman][b] ) for future use.[/b][/font][/size]
