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.
