Abstract: Nanosized Ca9.5Mg0.5(PO4)5.5(SiO4)0.5F1.5 was used as a biocatalyst for the synthesis of tetrahydrobenzo[b]pyrans derivatives via one-pot three-component reaction of various aldehydes, dimedone and malononitrile. The reactions were easily carried out at 60 °C under mild and heterogeneous… read more here.
