An efficient one-pot synthesis of 1,2,3-triazole derivatives of dihydropyrimidinones has been developed using two multicomponent reactions. The aldehyde-1,2,3-triazoles were obtained in good yields from in situ-generated organic azides and O-propargylbenzaldehyde. The target heterocycles were synthesized through the Biginelli reaction in which the aldehyde-1,2,3-triazoles reacted with ethyl acetoacetate
使用两个多组分反应已经开发出一种有效的一锅合成二氢嘧啶酮的1,2,3-三唑衍生物。从原位生成的有机叠氮化物和O-炔丙基苯甲醛以高收率获得醛-1,2,3-三唑。通过Biginelli反应合成目标杂环,其中在Ce(OTf)3作为催化剂存在下,醛-1,2,3-三唑与乙酰乙酸乙酯和尿素反应。使用电化学阻抗谱技术研究了合成的化合物对钢级API 5 L X52在1 M HCl中的腐蚀抑制作用。测量结果表明,这些杂环有望抑制钢的酸性腐蚀。
