ne-l,4,9-trione 9, a potential anthracycline precursor, has been prepared from 3,6-dimethoxybenzocyclobutenone 4 via quinone acetal and phthalide anion chemistry. Dials-Alder and electrophilic phthaloylation approaches to 9 were unsuccessful.
3,10-二甲氧基氯丁[b]蒽-1,4,9-三酮9,一种潜在的蒽环类前体,是由3,6-二甲氧基苯并环丁烯酮4经醌缩醛和邻苯二甲酸酯阴离子化学反应制得的。Dials-Alder和亲电邻苯二甲酰化方法均未成功达到9。
