Synthesis of 4-azo-butenolides
Pissurno, Ana Paula da Rocha,de Laurentiz, Rosangela da Silva
, p. 1874 - 1878 (2017)
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
