[BMIM]Cl catalyzed three component Mannich‐type reaction of 4‐(quinazolin‐4‐yloxy)benzenamine and aldehyde with dialkyl phosphite under microwave irradiation has been described. The salient features of the reaction leading to new α‐aminophosphonates include shorter reaction time and good yields. The method is environmentally friendly and does not require toxic catalysts or solvents. To the best of
[BMIM] Cl在微波辐射下催化了4-(喹唑啉-4-基氧基)苯甲胺和醛与亚磷酸二烷基酯的三组分曼尼希型反应。产生新的α-氨基膦酸酯的反应的显着特征包括较短的反应时间和良好的收率。该方法是环境友好的并且不需要有毒的催化剂或溶剂。据我们所知,这是[BMIM] Cl诱导α-氨基膦酸酯衍生物一锅合成的第一份报告。
