Abstract

PROCEDIMIENTO QUIMICO PARA LA RACEMIZACION DE UN A-AMINOACIDO. CONSISTE EN TRATAR UN A-AMINOACIDO OPTICAMENTE ACTIVO, DE FORMULA GENERAL (I), EN LA QUE R REPRESENTA UN GRUPO HIDROCARBILO O HETEROCICLICO OPCIONALMENTE SUSTITUIDO, CON UNA CETONA, DE FORMULA GENERAL (II), EN LA QUE R1 Y R2 SON IGUALES O DIFERENTES Y CADA UNO DE ELLOS REPRESENTA UN GRUPO HIDROCARBILO O HETEROCICLICO O BIEN R1 Y R2 UNIDAS COMPLETAN UN ANILLO DE CICLOALCANONA, EN PRESENCIA DE UN ACIDO ORGANICO Y, OPCIONALMENTE, SI SE DESEA, SE RESUELVE EL A-AMINOACIDO RACEMICO PARA OBTENER EL A-AMINOACIDO OPTICAMENTE ACTIVO, POR TRATAMIENTO CON UN AGENTE DE RESOLUCION QUE ORIGINA LA CRISTALIZACION DE LA SAL DEL A-AMINOACIDO, EN PRESENCIA DE UNA CETONA Y DE UN ACIDO ORGANICO. DE APLICACION EN LA SINTESIS DE COMPUESTOS FISIOLOGICAMENTE ACTIVOS, EN ESPECIAL COMO CADENAS LATERALES EN LOS ANTIBIOTICOS DE PENICILINA.
