Abstract

PROCEDIMIENTO PARA SEPARAR LOS ENATIOMEROS DE TRANS 3-HIDROXI-2,2-DIMETIL-4 (2-OXO-1,2-DIHIDROPIRIDIN-1-IL)-3,4-DIHIDRO-2H-1-BENZOP IRANO-6- CARBONITRILO (''I''), DONDE EN UN DISOLVENTE INERTE O EN UNA MEZCLA DE DISOLVENTES INERTES SE DISUELVE EL COMPUESTO ''I'' RACEMICO JUNTO CON UNA PEQUENA CANTIDAD DEL ENANTIOMERO (-)-''I'' O (+)-''I''; LA SOLUCION OBTENIDA SE INOCULA CON EL MISMO ENANTIOMERO, CON LO QUE PRECIPITA ESTE, QUE SE AISLA; EN EL FILTRADO SE DISUELVE MAS COMPUESTO ''I'' RACEMICO; LA SOLUCION SE INOCULA CON EL OTRO ENANTIOMERO, (+)-''I'' O (-)-''I'', RESPECTIVAMENTE, QUE ASI PRECIPITA Y SE AISLA, Y, SI SE DESEA, ESTE CICLO DE CRISTALIZACIONES SE REPITE UNA O VARIAS VECES.
