Abstract One-pot three-component synthesis of 1H-imidazol-5(4H)-one derivatives from (Z)-4-(arylmethylidene)-2-methyl-1,3-oxazol-5(4H)-one, methylamine, and N-benzylideneaniline has been developed using DBU (OAc) as an ionic liquid catalyst and TBAB as promoter. The reactions were carried out on heating at 75–80°C for 25–30 min to afford (4Z)-4-(arylmethylidene)-1-methyl-2-(2-phenylethenyl)-1H-imidazol-5(4H)-one
摘要 ( Z )-4-(芳基亚甲基)-2-甲基-1,3-oxazol-5(4 H )-one 的 1 H -imidazol-5(4 H )-one 衍生物的一锅三组分合成,已使用 DBU (OAc) 作为离子液体催化剂和 TBAB 作为促进剂开发了甲胺和N-亚苄基苯胺。反应在 75-80°C 下加热 25-30 分钟,得到 (4 Z )-4-(芳基亚甲基)-1-甲基-2-(2-苯基乙烯基)-1 H-咪唑-5( 4 H )-one 衍生物具有良好的收率。
