give the corresponding o-benzoquinones was examined. The trapping of o-benzoquinones with o-phenylenediamine immediately after oxidation was successfully used to isolate 2-substituted phenazines, the substituents being –CH3, –CH(CH3)2, –(CH2)2CO2H, –(CH2)2CO2CH3, –CH=CHCO2H, –CH=CHCO2CH3, –(CH2)2NHCOC6H5, and –CH2CH(NHCOC6H5)CO2CH3. Dopaquinone was identified in a protected form.
检测了包括 DOPA 在内的 4-取代儿茶酚与邻氯苯醌或硫酸铈 (IV) 的氧化反应,以产生相应的邻苯醌。氧化后立即用邻苯二胺捕获邻苯醌成功地用于分离 2-取代吩嗪,取代基为 –CH3、–CH(CH3)2、–(CH2)2CO2H、–(CH2)2CO2CH3、–CH =CHCO2H、–CH=CHCO2CH3、–(CH2)2NHCOC6H5 和 –CH2CH(NHCOC6H5)CO2CH3。多巴醌被鉴定为受保护形式。
