Abstract

NUEVO PROCEDIMIENTO PARA LA PRODUCCION DE ANTOCIANIDINAS POR REACCION DE UN DERIVADO 2,4 - DI - O - PROTEGIDO DE FLOROGLUCINALDEHIDO DE FORMULA VII (EN LA QUE PG1 Y PG2 REPRESENTAN CADA UNO UN GRUPO PROTECTOR DEL O), CON UN COMPUESTO DE FORMULA AR - CO - CH2OPG3, EN LA QUE AR SIGNIFICA UN ARILO, OPCIONALMENTE SUSTITUIDO, Y PG3 ES UN GRUPO PROTECTOR DEL O. LOS GRUPOS PROTECTORES DEL PRODUCTO DE CONDENSACION RESULTANTE SE PUEDEN CONVERTIR OPCIONALMENTE EN GRUPOS HIDROXILO LIBRES. LA INVENCION PROPORCIONA TAMBIEN UN NUEVO METODO PARA PRODUCIR LOS DERIVADOS DE FLUOROGLUCINALDEHIDO DE FORMULA VII, ASI COMO UN NUEVO PROCEDIMIENTO PARA PRODUCIR EL PROPIO FLOROGLUCINALDEHIDO.
