Abstract

La presente invención se refiere a procedimiento para preparar lactonas bicíclicas útiles en la preparación de compuestos tipo prostaglandina por reducción de manera altamente estereoselectiva de la mitad oxo de la cadena lateral de una lactona de la fórmula: (VER FIGURA) en donde L1 es (VER FIGURA) o una mezcla de (VER FIGURA) en donde R3 y R4 son hidrógeno, metilo, o flúor siendo iguales o diferentes, con la condición de que uno de R3 y R4 es flúor sólo cuando el otro es hidrógeno o flúor; en dondr R7 es 3(1)-(CH2)k-CH3, en donde k es 2 a 6 inclusive; (VER VFIGURA) en donde T es cloro, flúor, trifluorometilo, alquilo de 1 a 3 átomos de carbono, inclusive, y s es cero, uno, 2 ó 3, con la condición de que no más de dos T son otra cosa que alquilo, siendo las varias T iguales o diferentes, (VER FIGURA) en donde T y s son como se han definido arriba, ó (4) cis-CHCH2-CH2-CH3, con la condición de que R7 es (VER FIGURA) sólo cuando R3 y R4 son hidrógeno o metilo, siendo iguales o diferentes; y en donde R13 es un grupo directo de la fórmula (VER FIGURA) en donde R1 y R2 son hidrógeno, cloro fluor, bromo, alquilo de uno a 3 átomos de carbono, inclusive, o alcoxi de uno a 3 átomos de carbono, inclusive, siendo iguales o diferentes ó (VER FIGURA) en donde R1 y R2 son como se han definido arriba, siendo iguales o diferentes para cada anillo de fenilo; que comprende: reducir la lectona citada con un trialquil borohidruro de potasio de la fórmula (VER FIGURA) en donde m es cero, uno, 3 ó 3, con lo que se prepara un alcohol de la fórmula (VER FIGURA) en donde L1, R7 y R13 son como se ha definido arriba.The present invention relates to a process for preparing bicyclic lactones useful in the preparation of prostaglandin-like compounds by highly stereoselectively reducing the oxo half of the side chain of a lactone of the formula: (SEE FIGURE) where L1 is (SEE FIGURE) or a mixture of (SEE FIGURE) wherein R3 and R4 are hydrogen, methyl, or fluorine being the same or different, with the proviso that one of R3 and R4 is fluorine only when the other is hydrogen or fluorine; where R7 is 3 (1) - (CH2) k-CH3, where k is 2 to 6 inclusive; (SEE FIGURE) where T is chlorine, fluorine, trifluoromethyl, alkyl of 1 to 3 carbon atoms, inclusive, and s is zero, one, 2 or 3, with the proviso that not more than two T are anything other than alkyl , the various T being the same or different, (SEE FIGURE) where T and s are as defined above, or (4) cis-CHCH2-CH2-CH3, with the condition that R7 is (SEE FIGURE) only when R3 and R4 are hydrogen or methyl, being the same or different; and where R13 is a direct group of the formula (SEE FIGURE) where R1 and R2 are hydrogen, chloro fluorine, bromine, alkyl of one to 3 carbon atoms, inclusive, or alkoxy of one to 3 carbon atoms, inclusive , being the same or different or (SEE FIGURE) where R1 and R2 are as defined above, being the same or different for each phenyl ring; comprising: reducing the lectone mentioned with a potassium trialkyl borohydride of the formula (SEE FIGURE) where m is zero, one, 3 or 3, whereby an alcohol of the formula is prepared (SEE FIGURE) where L1, R7 and R13 are as defined above.
