Quinoline- and isoquinoline-5,8-diones react with 1-methoxycyclohexa-1,3-diene at 80 °C, the former giving 8-methoxy-1-aza-anthraquinone regiospecifically and the latter 5-methoxy-2-aza-anthraquinone regioselectively; in similar cycloadditions, substituted naphtho- and azanaphtho-quinones react with 1-dimethylamino-3-methyl-1-azabuta-1,3-diene at room temperature forming substituted mono- and di-aza-anthraquinones
喹啉和异喹啉-5,8-二烯与1-甲氧基环己-1,3-二烯在80°C下反应,前者在区域特异性地产生8-甲氧基-1-氮杂-蒽醌,后者5-甲氧基-2-氮杂-蒽醌区域选择性;在类似的环加成反应中,取代的萘醌和氮杂萘醌在室温下与1-二甲基氨基-3-甲基-1-氮杂-1,3-二烯反应,以高收率和高选择性形成取代的单-和二-氮杂-蒽醌。
