under ultrasound irradiation has been found to be effective for the three-component reaction involving ethyl-5- amino-1H-pyrazole-4-carboxylate, aromatic aldehydes and terminal alkynes in the presence of aerial oxygen. Methods: The catalyst / promoter / ligand free method afforded a range of pyrazolo[1,5-a] pyrimidines as potential and new cytotoxic agents. Results and Conclusion: While some of these
背景:发现乙酸在超声辐射下用作溶剂时,对于在空气中存在的5-氨基-1H-吡唑-4-羧酸乙酯,芳族醛和末端炔烃的三组分反应有效氧。 方法:无催化剂/无助催化剂/无配体的方法提供了一系列潜在的吡唑并[1,5-a]嘧啶和新的细胞毒性剂。 结果与结论:尽管这些化合物中的某些对两种乳腺癌细胞系显示出细胞毒性,但发现其中一种是有前途的。
