BRAIBANTE, Mara E. F. et al. The solvent free preparation of b-amino esters a,b-unsaturated ketones and esters with domestic microwave oven. J. Braz. Chem. Soc. [online]. 2006, vol.17, n.1, pp. 184-188. ISSN 1678-4790. http://dx.doi.org/10.1590/S0103-50532006000100026.
A series of b-amino esters a,b-unsaturated ketones and esters 4a-h and 6a-d derived from a-amino acids have been prepared starting from a-amino esters hydrochorides 2a-d with 1,3- dicarbonyl compounds 3a,b and 5 in presence of triethylamine. These compounds have been prepared under domestic microwave oven, under solvent free condition with and without solid support (K-10 or KSF).
Keywords : a-amino acids; solid support; microwave; a-amino esters.
