摘要：

DABCO (1,4-diazabicyclo[2.2.2]octane)-modified magnetite with silica-MCM-41 shell (Fe3O4@silica-MCM-41@DABCO) as an effective, magnetic and novel heterogeneous reusable nanocatalyst was synthesized and analysed using various techniques. Evaluation of the catalytic activity of this nanocatalyst was performed in the clean synthesis of substituted 2-aminodihydropyrano[3,2-b]pyran-3-cyano in high yields via in situ reaction of azido kojic acid, malononitrile and various aldehydes.
