Furo[2,3-d]pyrimidines were readily prepared via an inverse electron demand Diels–Alder (IDA) reaction between 2-aminofurans and 1,3,5-triazines. 2-Aminofurans proved to be productive dienophiles leading to the IDA product in moderate to good yields. This study further expanded the scope of 1,3,5-triazine IDA reactions with five-membered aromatic heterocycles as dienophiles.
通过2-氨基呋喃与1,3,5-三嗪之间的电子反需求Diels-Alder(IDA)反应,可以轻松制备Furo [2,3- d ]嘧啶。事实证明2-氨基呋喃是生产性的亲二烯体,以中等至良好的产率产生了IDA产物。这项研究进一步扩大了五元芳香族杂环作为双亲物的1,3,5-三嗪IDA反应的范围。
