Abstract
La presente invención se refiere a un procedimiento para la preparación de derivados de tetrahidrotieno (3,2-c) y (2,3-c) piridina, teniendo la tetrahidro-tieno (3,2-c)piridina la fórmula: (VER GACETA) y sus isómeros, los derivados de la tetrahidro-tieno (2,3-c) la fórmula: (VER GACETA) fórmulas en las que el hidroxilo OH está en posición 2 o en posición 4, R1, representa hidrógeno, un radical alcohilo o alcoxi inferior, un radical arilo, aralcohilo, R2 y R3 representan hidrógeno, un halógeno, un radical alcohilo o alcoxi inferior, un radical di(alcohilo inferior)amino, un grupo nitro, ciano o acetamido, o bien forman, en conjunto y con el núcleo de fenilo al que están unidos,un núcleo arómatico policíclico, estando R2 y R3 en posición 3, 4, 5 ó 6 cuando OH está en posición 2, y estando en posición 3, y 5, y siendo diferentes de hidrógeno cuando OH está en posición 4; caracterizado por hacer reaccionar, en un disolvente orgánico, particularmente etanol, propanol o dioxano, a una temperatura comprendida entre 50°C y la temperatura de ebullición del disolvente, un derivado de tetrahidrotieno (3,2-c)-piridina de fórmula: (VER GACETA) o un derivado de su isómero, tetrahidro tiene (2,3-c)-piridina, de fórmula: (VER GACETA) fórmulas en las que el radical R1 tiene los significados dados anteriormente, con formol H-CHO y un fenol de fórmula: (VER GACETA) en la que R2 y R3 tienen los significados dados anteriormente obteniendo así el derivado buscado, de fórmula Ia o Ib.The present invention relates to a process for the preparation of derivatives of tetrahydrothiene (3,2-c) and (2,3-c) pyridine, the tetrahydro-thiene (3,2-c) pyridine having the formula: (SEE GACETA) and its isomers, the derivatives of tetrahydro-thiene (2,3-c) the formula: (SEE GACETA) formulas in which the hydroxyl OH is in position 2 or in position 4, R1, represents hydrogen, a radical alcohol or lower alkoxy, an aryl, aralcohyl radical, R2 and R3 represent hydrogen, a halogen, an alcohol or lower alkoxy radical, a di (lower alcohol) amino radical, a nitro, cyano or acetamido group, or together form and with the phenyl nucleus to which they are attached, a polycyclic aromatic nucleus, R2 and R3 being in position 3, 4, 5 or 6 when OH is in position 2, and being in position 3, and 5, and being different from hydrogen when OH is in position 4; characterized by reacting, in an organic solvent, particularly ethanol, propanol or dioxane, at a temperature between 50 ° C and the boiling temperature of the solvent, a tetrahydrothiene (3,2-c) -pyridine derivative of the formula: ( SEE GAZETTE) or a derivative of its isomer, tetrahydro has (2,3-c) -pyridine, of formula: (SEE GAZETTE) formulas in which the radical R1 has the meanings given above, with formaldehyde H-CHO and a phenol of formula: (SEE GAZETTE) in which R2 and R3 have the meanings given above, thus obtaining the desired derivative, of formula Ia or Ib.
