Journal of the Brazilian Chemical Society, Campinas, v. 22, n. 3, p. 598-603, 2011.e- 1678-4790http://repositorio.bc.ufg.br/handle/ri/15392This work describes the direct synthesis of 3-bromotetronamides in good yields through the reaction of 3,4-dibromofuran-2(5H)-one, obtained from furfural, with primary and secondary amines. Aromatic amines were more tolerated than aliphatic and heteroaromatic ones. The X-ray structures of five derivatives are described.engAcesso AbertoEnaminonesTetronamidesButenolidesArtigo10.1590/S0103-50532011000300026
