摘要：
Novel kojic acid derivatives were prepared in good yields via one-pot, four-component reaction of aromatic aldehydes with Meldrum's acid, kojic acid, and ethanol in the presence of 1,4-diazabicyclo[2.2.2]octane immobilized on mesoporous SBA-15 as heterogeneous, nanoporous, solid-base catalyst. The compounds were evaluated for their antioxidant activity by 1,1-diphenyl-2-picrylhydrazyl radical-scavenging assay.
