Abstract
Método para sintetizar compuestos de fórmula (I) representada en la figura 1, dond: R' y R'' son independientemente hidrógeno o -C(O)OX, siendo X hidrógeno o un catión metálico o amonio; R3 es hidrógeno, halógeno, alquilo, CH2NHC(O)C(O)NH2, ciclopropilo; X2 es O o NR8, siendo R8 hidrógeno o alquilo C1-C4 opcionalmente sustituid con uno a tres átomos de flúor; el método comprende combinar un haluro de un alcalino o alcalinotérreo con un disolvente aprótico dipolar, básicamente amídico, agua y uno de los compuestos representados en la figura 2 (particularmente el cis-6-[3-(ciclopentiloxi)-4-metoxifenil)]-1-oxaespiro[2,5]octano-2,6-dicarbonitrilo), y calentar la combinación a una temperatura de al menos aproximadamente 60s durante varias horas, opcionalmente en una atmósfera inerte, precipitar un compuesto de fórmula (I) por adición de una base fuerte a dicha combinación, luego retirar el disolvente básicamente amídico y el agua de dicho precipitado, y opcionalmente purificar aún más el precipitado, o acidular el precipitado para obtener el ácido libre. En especial se incluyen compuestos intermedios y a una ruta sintética para obtener ácido 4-ciano-4-(3-ciclopentiloxi-4-metoxifenil)ciclohexanoico y sus análogos. Este ácido y sus análogos nombrados son selectivos inhibidores del sitio catalítico en la isoenzima fosfodiesterasa denominada IV ("PDE IV") y por ello los ácidos son útiles en el tratamiento de ciertas enfermedades que se pueden aliviar afectando a la enzima PDE IV y sus subtipos.Method for synthesizing compounds of formula (I) represented in figure 1, where: R 'and R' 'are independently hydrogen or -C (O) OX, where X is hydrogen or a metal or ammonium cation; R3 is hydrogen, halogen, alkyl, CH2NHC (O) C (O) NH2, cyclopropyl; X2 is O or NR8, with R8 being hydrogen or C1-C4 alkyl optionally substituted with one to three fluorine atoms; the method comprises combining a halide of an alkaline or alkaline earth with a dipolar aprotic solvent, basically amidic, water and one of the compounds represented in figure 2 (particularly cis-6- [3- (cyclopentyloxy) -4-methoxyphenyl)] -1-oxaspiro [2,5] octano-2,6-dicarbonitrile), and heating the combination to a temperature of at least about 60s for several hours, optionally in an inert atmosphere, precipitating a compound of formula (I) by addition from a strong base to said combination, then remove basically amidic solvent and water from said precipitate, and optionally further purify the precipitate, or acidify the precipitate to obtain the free acid. In particular, intermediate compounds and a synthetic route to obtain 4-cyano-4- (3-cyclopentyloxy-4-methoxyphenyl) cyclohexanoic acid and its analogs are included. This acid and its named analogues are selective inhibitors of the catalytic site in the isoenzyme phosphodiesterase called IV ("PDE IV") and therefore the acids are useful in the treatment of certain diseases that can be alleviated by affecting the enzyme PDE IV and its subtypes .
