Both reactions occurred at 80 oC. 1, 8-dioxo-octahydroxanthens has been synthesized under solvent-free conditions and water is used as a green solvent for the synthesis of 1, 8-dioxo-decahydroacridines. This methodology offers several advantages such as very simple work-up procedure, short reaction times, and mild reaction conditions. }, keywords = {Aluminium dodecyl sulfate trihydrate,Lewis acid,Lewis acid surfactant catalyst,Xanthenes,1,8-Dioxo-octahydroxanthens,Acridinediones,1,8-Dioxo-decahydroacridines,multi component reactions,Green chemistry}, url = {https://ijsts.shirazu.ac.ir/article_3010.html}, eprint = {https://ijsts.shirazu.ac.ir/article_3010_3dd7645f8b7ba778acaee90a7b5d582d.pdf} }
