Description

Compounds The present invention relates to new compounds, in particular to new polyazabicyclic compounds; to processes for their production; to new metal complexes of the new polyazabicyclic compounds; and to the use of the new metal complexes as bleach catalysts.
The present invention provides new compounds having the formula:
in which R is hydrogen, C1-C4alkyl, C1-C4alkoxy, halogen, amino, nitro, cyano, sulfo or sulfonamido; R1 is hydrogen or C1-C4allyl; Z is C2-C6alkylene; and n is O or 1; as well as salts thereof. The bonds denoted represent either a single or a double bond.
-C,-C4alkyl groups R or R1 include methyl, ethyl, n-propyl, isopropyl and n-butyl, with methyl being preferred.
C1-C4alkoxy groups R include methoxy, ethoxy, n-propoxy, isopropoxy and n-butoxy, with methoxy being preferred.
When R is halogen, it is preferably fluorine, chlorine, bromine or iodine, especially chlorine.
C2-C6alkylene groups Z include ethylene, n-propylene, methylethylene, n-butylene, n pentylene and n-hexylene, ethylene groups being preferred.
Salts of the compounds of formula (1) are preferably mineral acid salts such as hydrochloride, nitrate, sulfate and phosphate salts.
When n is 1, preferred compounds according to the present invention are those having the formula:
in which each of the bonds denoted ~ preferably represents a single bond and R and R, have their previous significance; as well as salts thereof.
When n is 0, preferred compounds according to the present invention are those having the formula:
in which each of the bonds denoted ~ preferably represents a single bond and R and R1 have their previous significance; as well as salts thereof.
The compounds of formula (2) are especially preferred. The preferred compound of formula (2) is 3,6,9,15-tetrakis(methyl)-3,6,9,15-tetraazabicyclot9.3.1]pentadecane as well as the tetrahydrochloride salt thereof.
The compounds of formula (1) may be produced, for example, in a first process by a) firstly conducting a cyclisation reaction by reacting a compound having the formula:
in which R has its previous significance and Y is a leaving group; with a compound having the formula:
in which Z and n have their previous significance and X is hydrogen or an amine protecting group, to obtain a compound having the formula:
in which R, Z, X and n have their previous significance; and then b) when R1 is a C1-C4alkyl group, reacting the compound of formula (6) with an alkylating agent which is capable of converting each of the groups N-X into an N-C1-C4alkyl group, to produce a compound of formula (1).
The leaving group Y in the reactant of formula (4) may be, e.g., a hydroxy, a chloro-, a bromo-, a mesyloxy-, a tosyloxy- or a C1-C4alkoxycarbonyl group. Each of the NH2- groups in the reactant of formula (5) is preferably in a protected form, for example it may be protected, prior to reaction with the compound of formula (4), by converting the respective hydrogen groups X into an amine protecting group, for example, a tosylate or trifluoroacetate group.
After the reaction of the compound of formula (4) with the compound of formula (5), the protecting groups X in formula (6) are removed prior to the reaction of the compound of formula (6) with the alkylating agent. The methods of removing such protecting groups X are well known. For example, if the protecting group X is a tosylate group, this may be removed, e.g., by treating the protected compound of formula (6) with a mineral acid, with an alkali metal in liquid ammonia, with HBr and phenol or with lithiumaluminium hydride.
The alkylation of the compound of formula (6) may be conducted, e.g., by reacting the compound of formula (6) with a C1-C4alkyl halide, a C,-C4alkyl sulfate, a C1-C4 alkanol or, preferably in the case of a methylation of a compound of formula (6), with formaldehyde in the presence of formic acid (Leuckart-Wallach reaction).
Finally, if desired, a compound of formula (1) in which one or more bonds denoted ~ are double bonds may be converted into a partly or fully saturated counterpart, for example by hydrogenation. The hydrogenation may be conducted, for example in an atmosphere of hydrogen over a catalyst such as Raney nickel.
The starting materials of formula (4) and (5) are known compounds which can be produced by known methods.
In a modification of this first process, the compounds of formula (1) in which one or more bonds denoted ~ are single bonds may be produced by reacting a compound having the formula:
in which R and Y have their previous significance; with a compound having the formula (5) to obtain a compound having the formula:
in which Z, X and n have their previous significance; and then b) when R1 is a O1-C4alkyl group, removing the protecting groups X and reacting the compound of formula (6A) in which X is hydrogen with an alkylating agent which is capable of converting each of the groups N-H into an N-C1-C4alkyl group, to produce a compound of formula (1).
Some of the starting materials of formula (4A) are known compounds and may be produced by methods which are known per se. For example, the compound of formula (4A) in which R is hydrogen and Y is hydroxy is a known compound and may be obtained by the hydrogenation of pyridine-2,6-dimethanol, or by the hydrogenation of pyridine-2,6dicarboxylic acid or the dimethyl ester thereof. On the other hand, the compounds of formula (4A) in which Y is a tosyloxy group are new compounds and, as such, form a further aspect of the present invention.
The compounds of formula (1) are capable of forming complexes with heavy metals, in particular manganese in the oxidation numbers 11, III, IV and/or V; copper in the oxidation numbers I and/or ll; cobalt in the oxidation number il and/or Ill; zinc in the oxidation number ll; iron in the oxidation numbers 11, Ill and IV; vanadium in the oxidation numbers Ill, IV and V; and titanium in the oxidation numbers Ill and IV.

1.18 g of the compound of formula (102) are dissolved in 12 ml of distilled water and are treated with 0.6 g of 5% Rh/C. The resulting solution is stirred ovemight at 25"C. in an atmosphere of hydrogen and at a pressure of 3 bar. After completion of the hydrogenation, the catalyst is filtered off and the filtrate is concentrated and dried under high vacuum. 1.22 g (91% of theory) of the compound of formula (103) are obtained as a yellow powder. NMR analysis of the compound gives: 13C NMR (D20) & 23.5, 28.1(6-ring CH2), 51.1, 45.4, 46.1(12-ring CH2), 53.2CH) C11H24N4 x 4HCI (358.19).
D) Production of 3,6,9,1 5-tetrakis(methyl)-3,3,9, 1 5-tetraazabicyclo[9 .3.1 ipentadecane- tetrahydrochloride having the formula:
1.08 g of the tetrahydrochloride compound of formula (103) are dissolved in 3 ml of distilled water to give a clear yellowish solution. With cooling, 4 ml of 50% aqueous sodium hydroxide solution are added, whereupon a light-yellow suspension is formed. The solid material, the free amine derived from the tetrahydrochloride compound of formula (103), is filtered off and sucked dry. With cooling, 0.98 g of the moist free amine is added to 8 ml of formic acid. To the clear colourless solution so obtained, there are added 6.4 ml of formaldehyde, over 30 minutes at 5"C. The reaction mixture is then heated for 40 hours under reflux. The resulting clear yellow solution is diluted with 5 ml of water. The pH of the diluted solution is adjusted to 11 by the addition of 50% aqueous sodium hydroxide solution, with cooling. The aqueous alkaline solution is then extracted three times with dichloromethane, using 15 ml of dichloromethane for each extraction. The resulting organic phases are combined, dried over anhydrous sodium sulfate, concentrated and dried under high vacuum. 620 g of crude product are obtained which are dissolved in 2 ml of conc. hydrochloric acid, with cooling.

The formation of the metal complex is monitored spectrometrically.
B) The bleach-promoting action of the manganese complex obtained in part A) is determined as follows. Using a Linitest device, each of the beakers is filled with 80 ml of test liquid, 2.5 g of tea-stained cotton and 7.5 g of white cotton, as ballast. The test liquid contains H202 (8.6 mmol/l)and the manganese complex obtained in part A) (5 x 106 mol/l) dissolved in borax buffer (0.03 mmol/pH 10). The test liquid is heated to 400 C. and held at this temperature for 30 minutes. The brightness value of the tea-stained cotton is determined, before and after treatment, using an ICS SF 500 spectrophotometer. The results obtained show that the manganese complex obtained in part A) exerts a bleach-promoting effect.
