Introduction
Porphyrins bearing reactive hydroxy and amino substituted phenyl rings in meso-positions present a considerable interest for synthetic organic chemistry. Modification of their structure can afford porphyrins with various substituents that can interact with metal atoms in the inner reaction site of the macrocycle. Introduction of long-chain substituents allows
to immobilize porphyrins on different carriers and favors the formation of supramolecular nanostructures. Acylation is one of the common methods employed for modification of active substituents.
We have earlier reviewed acylation of hydroxyphe-nylporphyrins.[1] The current paper focuses on the amino group as the porphyrin modification site. The amide bond, formed as a result of acylation, is stronger and more rigid
compared to the ester bond, which renders the modified porphyrins less prone to hydrolysis.
Many protocols of aminophenylporphyrin acylation can be found in literature. The common acylation agents include various carboxylic acid derivatives: chloroanhydrides,[2-13] anhydrides,[14-19] and carboxylic acids themselves as well. [2o-26] jn the latter case the common solvents are methylene chloride,[2426] THF[22'23,25] and chloroform.[2021] The reaction temperature varies from 0 °C to ambient temperature.[20-26] It should be noted that when carboxylic acids are employed for acylation, activating agents must be added: N,N'-dicyc-lohexylcarbodiimide,[20,21,24-26] 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDAC)[22,23] or mixtures of 2-chloro-4,6-dimethoxy-1,3,5-triazine (CDMT) with ^-methylmorpholine.[22] As a catalyst, N,N-dimethylamin-opyridine (DMAP) is generally used.[21-23,25]
The current paper covers our research on optimal acylation conditions affording maximal yield of acylamido-phenylporphyrins.
Results and Discussion
Comparatively available meso-aminophenyltriphenyl-porphyrins 5 and meso-aminophenyl-#-octaalkylporphyrins 6 (which are closer by structure to natural porphyrins) were used as model compounds.
The synthesis of aminophenylporphyrins 5, 6 was performed as a two-step procedure. First, nitrophenylporphyrins 1, 4 were obtained (Schemes 1-3); their following reduction by tin(II) chloride in the presence of hydrochloric acid, similarly to the known procedures,127-281 gave the target products 5, 6 (Scheme 4).
The starting meso-nitrophenyltriphenylporphyrins 1 were synthesized by a "mixed aldehyde" condensation of ni-trobenzaldehyde isomers and benzaldehyde with pyrrol in a mixture of xylene-chloroacetic acid, similarly to[1], however, as nitroporhyrins possess low polarity, the crude porphyrin mixtures were reduced to aminophenylporphyrins without isolation followed by chromatographic separation from the

accompanying meso-tetraphenylporphyrin 2 (Schemes 1, 4). 5-(4-Nitrophenyl)-10,15,20-triphenylporphyrin (1, 4-NO2) was also obtained by nitration of meso-tetraphenylporphyrin 2 (side product of the "mixed aldehyde" condensation) with sodium nitrite in trifluoroacetic acid, similarly to [29,30] (Scheme 2), with subsequent reduction, which afforded significantly increased total yield of aminophenylporphyrin 5 (4-NH2).
The isomeric 5-nitrophenyl-2,3,7,8,12,18-hexamethyl-13,18-di-«-amylporphyrins (4) were synthesized via condensation of 4,4'-dimethyl-3,3'-di-«-amyldipyrrolylmethane[31] with 2-formyl-3,4-dimethylpyrrole[31] in butanol containing hydrobromic acid with formation of the corresponding bila-diene 3 and its further treatment with nitrobenzaldehydes, similarly to[31,32] (Scheme 3).
Acylation of aminophenylporphyrins with EDAC-activated caboxyilic acids in the presence of DMAP was performed in a similar manner to acylation of hydroxy-phenylporphyrins[1] (Scheme 4), however the process has its peculiarities. While the formation of esters requires a slight excess of the acid and EDAC (~1.1 eq.) and the reaction time is usually 3 h,[1] the formation of amides requires a double amount of the acid and EDAC (~2.0 eq.) and the reaction time increases considerably (a full day or more). The yield of amides is usually higher than that of esters (for ~15%).
The influence of the nature of acids used for acylation on the reaction time and amide yield was studied. Aliphatic and aromatic carboxylic acids give the same yields but intraduction of electron-withdrawing fluorine atoms into the aliphatic chain results in a significant increase of the reaction time and a dramatic decrease of the yield, while using sterically strained a-amino acids results in increased reaction time with the same yield. Moreover, in the two latter cases the amount of the activating agent must be increased.
The position of amino group that is to undergo acyla-tion in the phenyl ring has a strong influence on the yield of the amide products: it decreases from the easily accessible para- and meta-positions to the hindered ortho-position.. In the case of 6 (2-NH2) the reaction does not occur at all. Comparing 5 (4-NH2) to 6 (4-NH2), the amide yield is about the same, while 6 (3-NH2) affords almost twice less amide while the reaction time increases greatly.
Experimental
Electronic absorption spectra were recorded in chloroform on a SPEC SSP-715 scanning spectrophotometer, IR spectral data were obtained on Avatar 360 FT-IR instrument (in KBr pellets), and proton magnetic resonance spectra (1H NMR) were recorded on a Bruker 500 in deuterated chloroform (with TMS as the internal
standard). Thin layer chromatography (TLC) was performed on Silufol® plates.

The reaction mixture was refluxed under argon atmosphere for 0.5 h and then for an additional 1 h in air. The solvent was removed by steam distillation, the residue was filtered, washed with water and dried. The residue was then dissolved in chloroform and subjected to column chromatography on Al2O3 (Brockmann grade III) using chloroform as the eluent. The dark-red band was collected, which corresponds to a mixture of porphyrins. Chloroform was evaporated and the remaining mixture was treated with 100 ml of hydrochloric acid containing 10.0 g SnCl2-2H2O and stirred for 2 h at 65 °C (water bath). The mixture was then diluted with 150 ml of water, filtered and the precipitate was washed with water, aqueous ammonia, again water and dried at ambient temperature to a constant weight. The precipitate was then dissolved in 50 ml of chloroform and subjected to column chromatography on Al2O3 (Brockmann grade III) eluting with chloroform. The dark-red band of the TPP and mono-aminophenylporphyrin was collected. The porphyrins were isolated by a secondary chromatographic separation on Al2O3, chloroform as the eluent. The solvent was evaporated and the porphyrins were precipitated with methanol. Yield - 1.7 g (15.0%) (5 4-NH2) and 2.25 g (27.0%) 2.
b) To a solution of 2.25 g (3.66 mmol) of tetraphenylpor-phyrin 2 in 40 ml of trifluoroacetic acid 0.5 g (7.25 mmol) of sodium nitrite in 3 ml of water was added. The reaction mixture was stirred for 3 min and poured into 250 ml of water. The precipitate was filtered, washed with water and stirred in 100 ml of hydrochloric acid containing 10.0 g (44.3 mmol, ~4.5-fold excess) of SnCl2-2H2O for 1 h at 80 °C, the mixture was then diluted with 100 ml of water, the precipitate was filtered, washed with water, diluted aqueous ammonia and again water, and dried to constant weight. The precipitate was then dissolved in 50 ml of chloroform and subjected to column chromatography on Al2O3 (Brockmann grade III) eluting with chloroform. The eluate was evaporated and the porphyrin was precipitated with methanol. Yield - 1.3 g (56.7%) (in terms of 2). The total yield of the two steps - 3.0 g (26.5%) (in terms of pyrrole).
