BRAIBANTE, Hugo T. S.; BRAIBANTE, Mara E. F.; ROSSO, Giovanni B. y ORIQUES, Daniela A.. Preparation of b-enamino carbonylic compounds using microwave radiation/K-10. J. Braz. Chem. Soc. [online]. 2003, vol.14, n.6, pp. 994-997. ISSN 1678-4790. http://dx.doi.org/10.1590/S0103-50532003000600016.
The preparation of b-enamino ketones and esters using the methodology of the reactions on solid support coupled with microwave irradiation is described. The reaction of cyclic, acyclic and a-chloro-substituted b-dicarbonyl compounds with amines or their corresponding ammonium acetates was carried out using K-10 as solid support and a domestic microwave oven as the radiation source to give b-enamino carbonylic compounds in good yields.
