An organophosphoric acid catalyzed [3+3] cyclization of 2-arylidene-indan-1,3-diones with enaminones has been established, which afforded a series of structurally diverse indenoquinolinedione derivatives in moderate to excellent yields. This [3+3] cyclization has some advantages such as mild reaction conditions, readily available catalyst and wide substrate range. This work not only provides an efficient method for constructing biologically important 1,4-dihydropyridine motif, but also suggests a possible reaction pathway and activation mode, therefore enriching the research contents of organophosphoric acid catalysis and [3+3] cyclization reactions.

Key words: organophosphoric acid, [3+3] cyclization, organocatalysis, enaminone, 1,4-dihydropyridine
