Abstract

LAS 1,4-DIHIDROPIRIDINAS 4-SUSTITUIDAS SE PREPARAN MEDIANTE UNA REACCION DE CICLOADICION EN QUE LA CICLACION SE LLEVA A CABO HASTA EL FINAL, DESPUES DE UNA REACCION TERMICA, MEDIANTE LA ADICION DE UN ACIDO. LA FELODIPINA, UN VASODILATADOR, SE PREPARA MEDIANTE UNA REACCION DE CICLOADICION DE 3-AMINOCROTONATO DE ETILO CON UNA DICLOROBENCILINA SUSTITUIDA DE MANERA ADECUADA BAJO CONDICIONES DE REACCION CON LO QUE EL PRODUCTO SE CRISTALIZA FUERA DE LA SOLUCION DE REACCION Y SE PUEDE AISLAR DIRECTAMENTE MEDIANTE UN PROCESO DE FILTRACION.
