A simple one-pot method for the preparation of 7-amino-2,4-dioxo-5-aryl-1,2,3,4-tetrahydropyrido[2,3-
d]pyrimidine-6-carbonitriles 4 from aromatic aldehydes, malononitrile and 4(6)-aminouracil in the presence of ZrO2
nanoparticles (ZrO2 NPs) as an efficient heterogeneous catalyst is described. The procedure has the advantages of high
yields (86-97%), short reaction time (2h) and an environmentally friendly specificity....
本研究介绍了一种以芳香醛、丙二腈和 4(6)-氨基尿嘧啶为原料,在 ZrO2 纳米粒子(ZrO2 NPs)作为高效异相催化剂存在下制备 7-氨基-2,4-二氧代-5-芳基-1,2,3,4-四氢吡啶并[2,3-d]嘧啶-6-甲腈 4 的简单一锅法。该过程具有产率高(86-97%)、反应时间短(2 小时)和环境友好的特异性等优点....。
