An operationally simple green procedure for the synthesis of dihydropyrimido[4,5-d]pyrimidinetriones using CuI nanoparticles as a highly efficient catalyst
An efficient and direct procedure for the synthesis of pyrimido[4,5-d]pyrimidine-2,4,7-trione derivatives has been described under microwave-assisted conditions. Reaction of 6-amino-1,3-dimethyluracil with aromatic aldehydes resulted in the formation of pyrido[2,3-d:6,5-d] dipyrimidine-2,4,6,8-tetrone derivatives.
已经描述了在微波辅助条件下合成嘧啶并[4,5 - d ]嘧啶-2,4,7-三酮衍生物的有效和直接的方法。6-氨基-1,3-二甲基尿嘧啶与芳族醛的反应导致吡啶并[2,3- d:6,5 - d ]二嘧啶-2,4,6,8-四氢呋喃衍生物的形成。
