Nanocrystalline TiO2, via green combustion synthesis, as an efficient and reusable catalyst for the preparation of 1,8-dioxooctahydroxanthenes and 1,8-dioxodecahydroacridines

摘要

Nanocrystalline TiO2 is synthesized using a green combustion method and used as a recyclable catalyst for the one-pot multicomponent synthesis of 1,8-dioxodecahydroacridines and 1,8-dioxooctahydroxanthenes, under solvent-free conditions. This method is mild, environmentally friendly, inexpensive and highly effective for obtaining good to excellent yields of the products. Copyright (C) 2015 John Wiley & Sons, Ltd.
