Abstract
Procedimiento para la obtención de L-Cisteinas N-Monosustituidas por vía electroquímica. El procedimiento para la obtención de L-cisteinas N- monosustituidas (I) , donde R{sup,1 es alquilo C{sub,1 -C{sub,5 , NH{sub,2 , o NHR{sup,4 , donde R{sup,4 es alquilo C{sub,1 -C{sub,5 ; R{sup,2 es H, benzoilo, carbamoilo, formilo o alcanoil C{sub,1 -C{sub,7 ; y R{sup,3 es H, alquilo C{sub,1 -C{sub,5 , amino, o un catión de un metal alcalino o alcalinotérreo, comprende la reducción electroquímica de una L-cistina N, N"''-disustituida de fórmula general (II), en medio básico, en una célula electroquímica que comprende, al menos, un cátodo, un ánodo, un catolito y un anolito separados por un medio adecuado, a una temperatura entre 0 y 90ºC y una densidad de corriente entre 1 y 500 mA/cm{sup,2 . Un ejemplo de estos compuestos es la N-acetil-L-cisteina útil como mucolítico, antioxidante y anticanceroso.
