Mex. Chem. Soc [online]. 2019, vol.63, n.4, pp.199-207.  Epub Sep 14, 2020. ISSN 1870-249X.  https://doi.org/10.29356/jmcs.v63i4.865.

In this paper, we report the catalyst-free three-component synthesis of 1,8-dioxooctahydroxanthenes in magnetized water as a green solvent. The reaction of aldehydes and 1,3-cyclohexanedione/dimedone in magnetized water gives the 9-substituted 1,8-dioxooctahydroxanthene derivatives. This green method offers the advantages of short reaction times, low-cost, simple work-up procedure, quantitative reaction yields, and no need for an organic solvent.

Keywords : 1,8-dioxooctahydroxanthenes; catalyst-free; magnetized water.
