2,4-Dimethoxy-1,3-diazaanthracene (DDA) has been prepared from the known 2,4-dichloro-1,3-diazaanthracene by methoxide displacement of the chloro-substituents and shown to react as a diene in Diels-Alder reactions with electron-deficient and ring-strained dienophiles. Sodium hydroxide fusion is used to transform the DDA adducts to uracil derivatives.
2,4-二甲氧基-1,3-二氮杂蒽 (DDA) 是由已知的 2,4-二氯-1,3-二氮杂蒽通过氯取代基的甲醇盐置换制备的,并显示在 Diels-Alder 中作为二烯反应与缺电子和环应变亲二烯体的反应。氢氧化钠熔融用于将 DDA 加合物转化为尿嘧啶衍生物。
