One-pot multicomponent reactions of 2,2’-alkylenedioxy-bridged or 4,4’-alkylenedioxy-bridged dialdehydes with excess ethyl acetoacetate and ammonium bicarbonate gave alkylenedioxy-bridged bisdihydropyridines in high yields. The structures of the synthetic bisdihydropyridines were characterized with 1H NMR, 13C NMR and HRMS spectra, and one representative compound was further confirmed by determination of its single crystal structure.

Key words: dihydropyridine, one-pot reaction, aldehyde, single crystal, ethyl acetoacetate
