oxindoles and triazolyl derivatives posses remarkable biological activities. In present work, we have described an efficient one pot four-component domino reaction of 1-(prop-2-ynyl)indoline-2,3-dione, cyclic 1,3-diketones, malononitrile and various aryl azides in DBU based ionic liquids [DBU-H]OAc and [DBU-Bu]OH under ultrasonic irradiation for the construction of heterocycles, comprising spiro-oxindole
螺环羟吲哚和三唑基衍生物具有显着的生物活性。在目前的工作中,我们已经描述了DBU基离子中1-(丙-2-炔基)二氢吲哚-2,3-二酮,环状1,3-二酮,丙二腈和各种芳基叠氮化物的高效一锅四组分多米诺反应在超声波辐射下,液体[DBU-H] OAc和[DBU-Bu] OH形成杂环,包括螺-氧吲哚,2-氨基-4 H-吡喃和1,2,3-三唑亚结构。已经研究了所有化合物对六种微生物菌株的抗微生物活性。所有化合物均显示出良好的抗菌活性。所有新合成的化合物在甲醇中均显示出较大的斯托克频移荧光。
