An expedient and eco-friendly protocol for the construction of CC CS bonds has been developed by Michael addition chalcones with various nucleophiles like malononitrile, 1,3-dimethylbarbituric acid, nitromethane, benzyl cyanide, thiols using water extract red mud (WERM) at room temperature. Red is by-product abundantly generated as wastes in aluminium industries this first report where WERM utilized profitably an alternative basic medium reaction. This reaction method not only environmentally benign cost-effective derived from waste material but also tolerated electronically diverse functional groups. Other notable advantages present are operational simplicity, no column chromatographic purification, excellent yields within short times, reusability media, scale up synthesis. Additionally, green applied to synthesize highly substituted pyridine derivatives.

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.
