A form of hydromagnesite (HM) with flower-like thin-sheet morphology was synthesized by an environmentally benign approach using simple conventional heating at moderate temperature without using any template in water as medium. The versatility of this HM catalyst was studied in the synthesis of flavanones, flavonols and the multicomponent synthesis of 1,4-dihydropyridines in water. The recyclability of catalyst was studied for six times and there was no appreciable loss in its catalytic activity. Copyright

An efficient and eco-friendly one-pot synthesis of polyhydroquinolines at ambient temperature from the multi-component reaction of aldehyde, 1,3-diketone, β-keto ester and ammonium acetate in ethanol medium is described. The probable mechanism of transformation is suggested. The features of this procedure are mild reaction conditions, no need of external catalyst, good yields and the operational simplicity at ambient temperature.
