environmentally benign one-pot method has been developed for the synthesis of 4-amino-5-arylpyrrolo[2,3-d]pyrimidines. Phthalimido acetophenones were reacted with cyanoacetamide to give 2-amino-4-phenyl-1H-pyrrole-3-carboxamides, which were further converted to 5-aryl-3H-pyrrolo[2,3-d]pyrimidin-4-ones. A novel method is also developed for the synthesis of 4-amino-5-iodopyrrolo[2,3-d]pyrimidines.
已经开发出一种有效且环境友好的一锅法,用于合成4-氨基-5-芳基吡咯并[2,3- d ]嘧啶。邻苯二甲酰亚胺苯乙酮与氰基乙酰胺,得到2-氨基-4-苯基-1- ħ吡咯-3-甲酰胺,其进一步转化为5-芳基-3- ħ吡咯并[2,3- d ]嘧啶-4-酮。还开发了用于合成4-氨基-5-碘吡咯并[2,3- d ]嘧啶的新方法。
