In this study, an efficient and convenient three-component cyclization protocol is presented for the synthesis of xanthene derivatives using a water extract red mud (WERM). Red produced in large quantities as waste aluminum industries, first report to use WERM renewable medium xanthenes. We focused our attention on domino condensation/Michael addition/intramolecular both experimentally density functional theory (DFT) studies, where formation chromenopyrimidines was suppressed simultaneously. Furthermore, innovation operates straightforward cost-effective manner, accommodates numerous groups, encompasses broad range substrates, produces exceptional yields, eliminates need column chromatography, enables scalable syntheses, allows reusability reaction media, all which contribute principles green sustainable chemistry.
