An efficient, catalyst-free, microwave-assisted approach has been developed for the synthesis of 4-azo-butyenolides derivatives by condensing tetronic acid with various anilines. This approach exhibited good functional group compatibility and produced the

Reaction of anilines 1a-d with retronic acid (2) or 1,3- cyclopentanedione (3) produced anilinolactones 4a-d and anilinocyclopentenone 5a, respectively, which were then condensed with benzaldehydes to yield 4- aza-1-arylnaphthalene lignan analogs 6-19.
