Abstract

Un método para la fabricacion de compuesto beta-cetoésteres que posee la formula (I), dicho método comprende los siguientes pasos: a)reaccionar unoo más activos alcoholicos que poseen la formula R-OH, en la que R posee como mínimo cincoátom os de carbono con un dicetano que posee la formula: (II), paraproducir un beta-cetoéster- que posee la formula (III) donde cada R se selecciona de modo independiente del grupo formado por hidrogeno y arilo,alquenilo y alquilo sustituidoo no sustituido, ramificado o lineal C1-C30, y b)reaccionar dicho beta-cetoéster- del paso a) con uno o más haluros deácido carboxílico que poseen la formula: B-C(O)-X, donde B se selecciona del grupo formado por arilo, alquenilo y alquiloC1-C10 lineal o ramificadosustituido o no sustituido y X se selecciona del cloruro o bromuro para producir un beta-cetoéster-.
