Description
Procedimiento para la preparación de arilamidas
de ácidos carboxílicos heteroaromáticos.
La presente invención se refiere a un
procedimiento para la preparación de arilamidas de ácidos
carboxílicos heteroaromáticos, por reacción de compuestos
halogenados heteroaromáticos con monóxido de carbono y aminas
aromáticas, en presencia de un catalizador y una base.
Las amidas preparadas según la invención poseen
la fórmula general
en la cual
significan
A^{1} nitrógeno o CR^{1},
A^{2} nitrógeno o CR^{2},
A^{3} nitrógeno o CR^{3},
A^{4} nitrógeno o CR^{4},
y A^{5} nitrógeno o CR^{5},
con la condición de que al menos uno de los
miembros de anillo A^{1} a A^{5} es nitrógeno y que no estén
unidos entre sí dos átomos de nitrógeno inmediatamente
adyacentes,
R^{1} hasta R^{5}, si están presentes, son,
de forma independiente entre sí, hidrógeno,
alquilo-C_{1-4} o arilo, siendo,
sin embargo, uno de los sustituyentes R^{1} hasta R^{5} un grupo
de la fórmula -OR, en la que R es un resto aromático o
heteroaromático eventualmente sustituido,
R^{6} es hidrógeno o
alquilo-C_{1-4}, y
R^{7} es un resto aromático o heteroaromático,
eventualmente sustituido, al que pertenecen, en especial, las
arilamidas de los ácidos piridín, pirimidín, pirazín y
1,3,5-triazin-carboxílicos.
Numerosos compuestos de esta estructura, en
especial aquéllos en los que uno de los sustituyentes R^{1} hasta
R^{5} es un grupo ariloxi (-OR) adyacente a un átomo de nitrógeno
de anillo, son importantes herbicidas (documentos
WO-A 94/27974, EP-A 0 053 011,
EP-A 0 447 004). La síntesis de estos compuestos
conocidos se realiza habitualmente a partir de los correspondientes
ácidos carboxílicos o derivados de ácidos carboxílico (cloruros
ácidos, ésteres, nitrilos). No obstante, éstos son a menudo de
difícil acceso y, por lo tanto, caros.
Misión de la presente invención fue, por tanto,
poner a disposición un procedimiento alternativo, a partir de
eductos de más fácil acceso.
De acuerdo con la invención, esta misión se
resuelve por los procedimientos según las reivindicaciones 1 y
13.
Se ha encontrado que compuestos halógenos de la
fórmula
en la que A^{1} hasta A^{5} tienen los
significados anteriormente mencionados y X es cloro, bromo o yodo,
reaccionan directamente con monóxido de carbono y una amina primaria
o secundaria de la fórmula
general
IIIR^{6}-NH-R^{7}
en la que R^{6} y R^{7} tienen los
significados anteriormente mencionados, en presencia de una base,
para formar los productos (1) deseados, con un rendimiento
cuantitativo correcto a regular, cuando se utiliza como catalizador
un complejo de paladio con una difosfina de la fórmula
general
IVR^{8}R^{9}P-[CH_{2}]_{n}-PR^{10}R^{11}
en la que significan R^{8} hasta R^{11}, de
forma independiente entre sí, fenilo o fenilo sustituido y n, 3 ó
4.
Tanto en estas definiciones como en lo sucesivo,
se entiende por alquilo C_{1-4} todos los grupos
alquilo lineales o ramificados, primarios, secundarios o terciarios,
con hasta 4 átomos de carbono. Por restos aromáticos o
heteroaromáticos se entienden en estas definiciones y en lo
sucesivo, especialmente sistemas mono- o policíclicos tales como,
por ejemplo, fenilo, naftilo, bifenililo, antracenilo, furilo,
pirrolilo, pirazolilo, tiofenilo, piridilo, indolilo o quinolinilo.
Éstos pueden portar uno o múltiples sustituyentes iguales o
diferentes, por ejemplo, grupos alquilo inferiores tales como
metilo, grupo alquilo halogenados tales como trifluorometilo, grupos
alcoxi inferiores tales como metoxi, o grupos alquiltio-
(alcanosulfonilo) o alcanosulfonilo tales como metiltio o
etanosulfonilo. Por fenilo sustituido se entienden, en especial,
grupos tales como (p)-fluorofenilo,
(p)-metoxifenilo,
(p)-tolilo o
(p)-trifluorometilfenilo.
Los compuestos halogenados (II) que sirven como
materiales de partida son compuestos conocidos, o se pueden preparar
de manera análoga a los compuestos conocidos. Se describen numerosos
compuestos de este tipo, por ejemplo, en los documentos
US-A 4 254 125 y EP-A 0 001 187.
Aquellos compuestos halogenados (II) en los que
los grupos de la fórmula -OR están unidos a uno de los átomos de
carbono adyacentes al átomo de nitrógeno de anillo, se preparan
convenientemente haciendo reaccionar un dihalogenuro de la fórmula
general
en la cual A^{1} hasta A^{5} tienen los
significados anteriormente mencionados, con la condición de que uno
de los restos R^{1} hasta R^{5} en uno de los átomos de carbono
adyacente a uno de los átomos de nitrógeno de anillo esté sustituido
con Z, que significa cloro, bromo o yodo, y X signifique, de forma
independiente, cloro, bromo o yodo, con un compuesto hidroxi
aromático o heteroaromático de la fórmula
general
VIR-OH
en la que R tiene el significado anteriormente
mencionado.
El procedimiento según la invención se adecua,
preferentemente, para la preparación de amidas (I) en las que
A^{2} significa nitrógeno y que forman con los restantes miembros
del anillo un anillo de piridina. Se prefieren de forma especial las
amidas (I) en las que R^{1} es un grupo de la fórmula -OR, en la
que R tiene el significado anteriormente mencionado.
De igual forma, se prefieren las amidas (I) en
las que A^{1} significa nitrógeno y que forma con los restantes
miembros del anillo un anillo de piridina,
aquéllas en las que A^{1} y A^{5} significan
nitrógeno y que forman con los restantes miembros del anillo un
anillo de pirimidina,
aquéllas en las que A^{1} y A^{4} significan
nitrógeno y que forman con los restantes miembros del anillo un
anillo de pirazina,
así como aquéllas en las que A^{1}, A^{3} y
A^{5} significan nitrógeno y que forman con los restantes miembros
del anillo un anillo de 1,3,5-triazina.
De las cuatro clases mencionadas en último lugar
se prefieren especialmente, una vez más, aquellas amidas en las que
R^{2} significa un grupo de la fórmula -OR, en la que R tiene el
significado anteriormente mencionado.
Adicionalmente, de las amidas (I) se prefieren
aquéllas en las que R es un grupo fenilo eventualmente sustituido.
Esto es especialmente válido para las amidas anteriormente
mencionadas con un anillo de piridina, pirimidina, pirazina o
1,3,5-triazina, en las que R^{1} o R^{2} es un
grupo de la fórmula -OH.
Se prefieren, igualmente, aquellas amidas en las
que R^{6} significa hidrógeno y R^{7} significa un grupo fenilo
eventualmente sustituido.
Como compuestos halogenados (II) se prefieren los
compuestos de cloro (X = Cl).
El complejo de paladio-difosfina,
con acción catalítica, se forma convenientemente in situ,
haciendo reaccionar paladio en forma elemental y finamente
distribuida (por ejemplo, paladio sobre carbono activo), una sal de
Pd(II) (por ejemplo, cloruro o acetato), o un complejo
adecuado de Pd(II) (por ejemplo,
dicloro-bis(trifenilfosfin)-paladio
(II), con difosfina. Preferentemente, paladio se utiliza en una
cantidad de 0,02 hasta 0,2% en moles de Pd(II), o 0,5 hasta
2% en moles (Pd(0) (como Pd/C), siempre referido al compuesto
halogenado (II). La difosfina se utiliza convenientemente en exceso
(referido a Pd), preferentemente en una cantidad de 0,2 hasta 5% en
moles, también referida al compuesto halogenado (II).
Como disolvente se pueden emplear tanto
disolventes relativamente apolares tales como, por ejemplo, tolueno
o xileno, como disolventes polares tales como, por ejemplo,
acetonitrilo, tetrahidrofurano o N,N-dimetilacetamida.
Como base se utiliza, preferentemente, una base
relativamente débil. Ésta no necesita ser soluble en el disolvente
empleado. Resultan adecuados, por ejemplo, los carbonatos tales como
carbonato sódico o carbonato de potasio, o acetatos tales como
acetato sódico. Con la base mencionada en último lugar se han
obtenido resultados especialmente adecuados.
La temperatura de reacción se encuentra,
preferentemente, entre 80 y 250ºC.
La presión de monóxido de carbono se encuentra,
preferentemente, entre 1 y 50 bar.
Los siguientes Ejemplos explican más
detalladamente la realización del procedimiento según la
invención.
En 420 ml de N,N-dimetilacetamida se
suspendieron 17,46 g (690 mmol) de hidruro sódico (al 95%). A 15ºC
se agregaron, gota a gota, durante 2 h, 106,7 g (658 mmol) de
3-(trifluorometil)fenol. La solución de fenolato obtenida de
esta forma se agregó, gota a gota, en el plazo de 2,5 h y bajo
nitrógeno, a una solución de 162,4 g (1,097 mol) de
2,6-dicloropiridina en 330 ml de
N,N-dimetilacetamida, calentada a 90ºC. Después de 3 h
adicionales de reacción, se enfrió la mezcla a temperatura ambiente,
se separó por filtración el cloruro sódico precipitado y se
concentró el filtrado. El residuo se recogió con tolueno y ácido
clorhídrico 0,1 N, la fase orgánica se lavó con una solución
saturada de cloruro sódico y se concentró. El residuo oleoso (aprox.
200 g) se destiló al vacío.
