Abstract
UN PROCEDIMIENTO PARA LA PRODUCCION DEL ESTE 5-METILICO Y (3S)-3-(1-BENCIL-3-PIRROLIDINILICO) DEL ACIDO (4S)-2,6-DIMETIL-4-(M-NITROFENIO)-1,4-DIHIDROPIRIDIN-3,5-DICARBOXILICO, DE FORMULA (III) POR REACCION DE UN DERIVADO DEL ESTER (3S)-3-(1-BENCIL-3-PIRROLIDINILICO) DEL ACIDO (4S)-2,6-DIMETIL-4-(M-NITROFENIL)-1,4-DIHIDROPIRIDIN-3,5-DICARBOXILICO DE FORMULA (I), DONDE RK ES UN RESTO ESTER SUSCEPTIBLE DE SER FACILMENTE ESCINDIDO POR HIDROLISIS CON UN ALCALI SIN AFECTAR A LOS OTROS GRUPOS, CON UN AGENTE ESTERIFICANTE METILICO, TAL COMO DIAZOMETANO, O UN HALURO DE METILO. ALTERNATIVAMENTE, EL COMPUESTO (III) PUEDE OBTENERSE POR HIDROLISIS DEL ESTER (I) O DE SUS DERIVADOS PARA DAR EL ESTER DE FORMULA (II) Y POSTERIOR TRATAMIENTO CON EL MENCIONADO AGENTE ESTERIFICANTE METILICO. EL ESTER (III) ASI OBTENIDOEJERCE UN EFECTO VASO-DILATADOR E HIPOTENSOR DE EFECTO DURADERO POR LO QUE ES UTIL PARA EL TRATAMIENTO DE CIERTOS ESTADOS PATOLOGICOS RELACIONADOS CON LA VASOCONSTRICCION Y LA HIPERTENSION.
