摘要
Tetrabutylammonium hexatungstate,[TBA]2[W6O19],has been used as an efficient,inexpensive,and recyclable green catalyst for the one-pot three-component synthesis of 1,8-dioxodecahydroacridines by the reaction of dimedone with aromatic or aliphatic aldehydes in the presence of a nitrogen source(ammonium acetate or aromatic amines) under neat conditions.There are several advantages to the current process over the standard procedures available in the literature,including shorter reaction times(7-14 min),higher yields,facile work-up,and minimal environmental impact.Furthermore,the catalyst can be conveniently recovered and reused.
