Description

The present invention relates to a process for preparing derivatives of perylenediimide of formula I, characterized by being substituted in positions 1, 6, 7 and / or 12 (bay positions).

STATE OF THE TECHNIQUE

10 Perimin-3,4,9,10-tetracarboxylic acid diimides, also known as perylenediimides (PDI) or as perylene bisimides (PBI), are very stable compounds both chemically and thermally, and also against electromagnetic radiation. The POIs absorb intensely in the ultraviolet-visible region of the electromagnetic spectrum, so they exhibit very vivid colorations that, depending on the

15 substituents that present, can vary from orange to blue, through red and green. The POIs are highly fluorescent, with quantum fluorescence yields that can reach the unit. Other properties of IDPs include their high electronic affinity and their great ability to transport electrons under the influence of an electric field. For all these characteristics, they are used

20 widely in the industry as dyes, pigments in paints and fluorescent agents. They are also used in research for the development of optical, electronic and electro-optical devices such as field effect transistors, light emitting diodes and photovoltaic devices (solar cells).

25 The optical, electronic and electro-optical properties of IDPs can be modified depending on the substituents. Important changes in the properties are obtained by introducing, modifying or varying the substituents on the bay positions (1, 6, 7 and / or 12) of the POI. The introduction on the bay positions (1, 6, 7 and / or 12) of Oalkyl and O-aryl groups, linked to the PDI by the oxygen atom, and azacycloalkanes, attached to

30 the PDI for the nitrogen atom, has been widely used.

The O- or N-substituted POIs in the bay positions are obtained in two stages. The first is to halogenate (chlorinate or brominate) the unsubstituted PDI. The POI (usually with chlorine) can be tetrahalogenated at positions 1, 6, 7 and 12. On the other hand, the PDI (usually with bromine) can be dihalogenated to obtain a mixture

of two regioisomers, 1,6-dibromoPDI (minor isomer) and 1,7-dibromoPDI (majority isomer), which cannot be separated by standard techniques.

In a second stage the halogen atoms (chlorine or bromine) are replaced by

5 reaction in basic medium, with alcoholates, phenolates or amines. In the case of IDPs disubstituted, the mixture of isomers 1.6 (minority) and 1.7 is still maintained (majority), although in some cases they can be separated by techniques chromatographic

10 These and other properties and characteristics of IDPs are found in many monographs and scientific articles, such as (a) F. Würthner. Chem. Commun. 2004, 1564-1579. (b) H. Langhals. Helv. Chim. Minutes 2005, 88, 1309-1343.

(c) A. Herrmann, K. Müllen. Chem. Lett. 2006, 35, 978-985. (d) F. Würthner. Pure Appl. Chem. 2006, 78, 2341-2349. (e) C. Huang, S. Barlow, S. R. Marder. J. Org.

15 Chem. 2011, 76, 2386-2407. (f) X. Zhan, A. Facchetti, S. Barlow, T. J. Marks, M. A. Ratner, M. R. Wasielewski, S. R. Marder. Adv. Mater. 2011, 23, 268-284. (g) C. Li, H. Wonneberger. Adv. Mater. 2012, 24, 613-636.

Therefore, these procedures have to be carried out in at least two stages, of

20 which one corresponds to a halogenation (chlorination or bromination) of the POIs to functionalize the positions that can be substituted. On the other hand, by means of the procedures described, only monosubstituted, disubstituted POIs (as a mixture of regioisomers, where the isomer 1.7 over 1.6) and tetrasubstituted isomers can be obtained.

Thus, it would be desirable to have an alternative, more selective and more efficient method, which would facilitate obtaining in one stage the substituted PDI compounds. It would also be desirable for the method to allow, in addition to monosubstituted POIs, disubstituted POIs in which the 1,6 isomer was higher

30 proportion Finally, a method would be needed that would make it possible to obtain the 1.12 isomer and trisubstituted PDI.

The compounds of the present invention contain one or more basic nitrogen and could therefore form salts with acids, both organic and inorganic. Examples of such salts include: salts with inorganic acids such as hydrochloric acid, hydrobromic acid, hydroiodic acid, nitric acid, perchloric acid, sulfuric acid or phosphoric acid; and salts with organic acids, such as methanesulfonic acid,

20 trifluoromethanesulfonic acid, ethanesulfonic acid, benzenesulfonic acid, ptoluenesulfonic acid, fumaric acid, oxalic acid, acetic acid, maleic acid, ascorbic acid, citric acid, lactic acid, tartaric acid, malonic acid, glycolic acid, succinic acid and propionic acid, between others. Some compounds of the present invention may contain one or more acidic protons and therefore may form

25 also salts with bases. Examples of such salts include: salts with cations

inorganic such as sodium, potassium, calcium, magnesium, lithium, aluminum, zinc, etc .; and salts formed with pharmaceutically acceptable amines such as ammonia, alkylamines, hydroxyalkylamines, lysine, arginine, N-methylglucamine, procaine and the like.

5 There is no limitation on the type of salt that can be used, provided that when used for therapeutic purposes are pharmaceutically acceptable. Be means pharmaceutically acceptable salts those salts that, at the discretion medical, are suitable for use in contact with the tissues of humans or other mammals without causing undue toxicity, irritation, allergic response or

10 similar. Pharmaceutically acceptable salts are widely known to any person skilled in the art.

The salts of a compound of formula I can be obtained during the final isolation and purification of the compounds of the invention or they can be prepared by

Treatment of a compound of formula I with a sufficient amount of the desired acid or base to give the salt in a conventional manner. The salts of the compounds of formula I can in turn be transformed into other salts of compounds of formula I by ion exchange by means of an ion exchange resin.

The compounds of formula I and their salts may differ in certain physical properties, but are equivalent for the purposes of the invention. All salts of the compounds of formula I are included within the scope of the invention.

The compounds of the present invention can form complexes with solvents in which they are reacted or from which they are precipitated or crystallized. These complexes are known as solvates. As used herein, the term "solvate" refers to a complex of variable stoichiometry formed by a solute (a compound of formula I or a salt thereof) and a solvent. Examples of solvents include

30 pharmaceutically acceptable solvents such as water, ethanol and the like. A complex with water is known as hydrate. Solvates of the compounds of the invention (or their salts), including hydrates, are included within the scope of the invention.

The compounds of formula I can exist in different physical forms, that is, in amorphous form and crystalline forms. Also, the compounds of the present invention

They may have the ability to crystallize in more than one way, a characteristic known as polymorphism. Polymorphs can be distinguished by several physical properties well known to those skilled in the art such as their x-ray diffractograms, melting points or solubility. All shapes

The physical compounds of the compounds of formula I, including all their polymorphic forms ("polymorphs"), are included within the scope of the present invention.

Some compounds of the present invention could exist in the form of several diastereoisomers and / or several optical isomers. The diastereoisomers can be separated by conventional techniques such as chromatography or fractional crystallization. Optical isomers can be resolved by using conventional optical resolution techniques, to give optically pure isomers. This resolution can be made on synthesis intermediates that are chiral or on products of formula I. Optically pure isomers can also be

15 obtained individually using enantiospecific synthesis. The present invention covers both the individual isomers and their mixtures (for example racemic mixtures or mixtures of diastereoisomers), whether they are obtained by synthesis or by physically mixing them.

As mentioned above, the method of the present invention allows substituents (R3) to be introduced in the bay positions of a POI at a stage in which a source of fluoride and an alcohol, thiol, selenol, amine or phosphine is involved.

As will be apparent to one skilled in the art, the precise method used for the

The preparation of a given compound may vary depending on its chemical structure. Also, in some of the procedures detailed below, it may be necessary or convenient to protect reactive or labile groups by conventional protecting groups. Both the nature of these protecting groups and the procedures for their introduction and elimination are well known and form

30 part of the state of the art (see for example Greene T.W. and Wuts P.G.M, "Protective Groups in Organic Synthesis", John Wiley & Sons, 4th edition, 2006). Whenever a protective group is present, a subsequent deprotection stage will be necessary, which is carried out under the usual conditions in organic synthesis, such as those described in the reference mentioned above.

Also, some compounds of the present invention can be obtained from other compounds of formula I by transformation reactions of suitable functional groups, in one or more stages, using reactions widely known in organic chemistry under the usual experimental conditions. These

5 interconversions can be carried out independently on R1, R2 and R3 e include:

the replacement of a primary or secondary amine by treatment with an alkylating agent under standard conditions, or by reductive amination, that is, by treatment with an aldehyde or ketone in the presence of a reducing agent such as sodium cyanoborohydride or sodium triacetoxyborohydride;

the transformation of an amine into a sulfonamide by reaction with a sulfonyl halide, such as sulfonyl chloride, optionally in the presence of amounts

Catalysts of a base such as 4-dimethylaminopyridine, in a suitable solvent such as dioxane, chloroform, dichloromethane or pyridine, optionally in the presence of a base such as triethylamine or pyridine;

the transformation of an amine into an amide under standard conditions;

20 the alkylation of an amide by treatment with an alkylating agent under basic conditions;

the conversion of an alcohol into an ether or ester under standard conditions; 25 the alkylation of a thiol to obtain a thioether, under standard conditions;

partial or total oxidation of an alcohol to obtain ketones, aldehydes or carboxylic acids under standard oxidation conditions;

30 the reduction of an aldehyde or ketone to alcohol, by treatment with a reducing agent such as sodium borohydride;

the reduction of a carboxylic acid or a derivative of carboxylic acid to alcohol by treatment with a reducing agent such as diisobutylaluminum hydride or LiAlH4;

the reduction of an amide to amine by treatment with a reducing agent such as LiAlH4;

the oxidation of a thioether to sulfoxide or sulfone under standard conditions;

5 the transformation of an alcohol into a halogen by treatment with SOCl2, PBr3, tetrabutylammonium bromide in the presence of P2O5, or PI3;

the transformation of a halogen atom into an amine by reaction with a

10 amine, optionally in the presence of a suitable solvent, and preferably heating; Y

the transformation of a primary amide into a -CN group or vice versa, of a -CN group into an amide by standard conditions.

Similarly, any of the aromatic rings of the compounds of the present invention may undergo aromatic electrophilic substitution or aromatic nucleophilic substitution reactions, widely described in the literature.

The compounds of formula II and III may be commercial or prepared by methods widely described in the literature from commercial products or by the interconversion reactions of functional groups described above for a compound of formula I, and may be conveniently protected.
