Definitions
- This invention relates to cyclohexadienediols which are of utility as chiral synthons.
- Cyclohexadiene-cis-diols are known. They can be prepared by microbiological transformation of benzene and substituted analogues, including benzoic acids.
- the cyclohexadiene-cis-diols of formula I may be converted to lactams of formula II which are themselves precursors of anti-viral compounds, to amino-acids of formula Ilia which are analogues of phenylglycine, to transition metal complexes, and also to compounds as shown in the accompanying Chart. All these conversions are facilitated by the ready availability of the starting material.
- the diols at the centre of the accompanying Chart can be produced by microbiological transformation from the corresponding (R) -substituted-benzoic acid A, B, C or D, or a more reduced precursor such as the
- R 3 respectively represent the alkyl groups of each of R 2 and R 3 as alkylcarbonyl.
- Ethers of formula I (R 2 and/or R 3 as alkyl) can be prepared by alkylation.
- R 2 and R 3 are preferably each CH-, or together are -C(CH 3 ) 2 -.
- Route i represents chemical acylation; routes i and ii represent biological acylation (using a lipase/ether, R 1 COOH).
- stereospecific deacylation suitable for route iii, is reaction of the substituted benzoate diester with water in the presence of a suitable lipase and co-solvent (or emulsifier).
- suitable lipases include those isolated from strains of Candida, Pseudomonas, Rhizopus and
- Suitable co-solvents include ethers (e.g. diethyl ether), ketones (e.g. acetone), CFC's and hydrocarbons alkanes (such as toluene, hexane or
- An example of biological esterification, suitable for route iv, is reaction with a suitable alkanol (e.g. C 1-8 ethanol) in the presence of a suitable lipase such as those listed above.
- a suitable lipase such as those listed above.
- suitable co-solvents include those listed above. Water is preferably excluded from the bulk phase.
- the esters can be subjected to trans-esterification, and interconverted.
- the esterified products can be acylated, and vice versa.
- An example of biological transesterification is reaction of the diester derivative with another
- Suitable co-solvents again include those listed above.
- Compounds of the invention may lose the chirality due to ring-substitution, on further reaction.
- the molecule as a whole may remain chiral, if there if a chiral substituent.
- the compounds of this invention can be used as chiral or prochiral intermediates in the synthesis of pharmaceuticals and agrochemicals and as the raw material for polyarylene-type polymers.
- Compounds of formula IA are particularly suitable for modification as substrates for the Strecker reaction, i.e. using NH 3 and HCN, or any of the various appropriate modifications described in the Merck Index, to provide analogues of phenylglycine. Modification from the acid/ester to aldehyde group can be conducted by
- the products are semi-synthetic penicillin-type compounds having additional chiral centres.
- inositol phosphate is in areas as diverse as control of diabetes and clinical depression.
- Inositol triphosphate/tetraphosphates have until recently been available only by extraction from natural sources. Thus, only the parent molecules are produced, while the generation of analogues with differing
- Ley et al generated inositol phosphate (1,4,5) P 3 and two derivatives of formula VII using benzene cis-glycol as a starting material.
- Various 9-substituted purines are known as antiviral and anti-neoplastic agents.
- One such compound known as AZT, has been used for the treatment of AIDS.
- AZT AZT
- Carbovir a compound known as Carbovir (see formula V) has been disclosed by Vince et al, Biochem. and Biophys. Res. Com. 156 No. 2 (1988) 1046-1053, as a potent and selective anti-HIV agent.
- Carbovir may be synthesised from the known ⁇ -lactam, 2-azabicyclo [2.2.1] hept-5-en-3-one.
- the synthesis, from the corresponding ring-opened amino-acid, is described in GB-A-2217320.
- the ⁇ -lactam can be prepared by reacting cyclopentadiene with tosyl cyanide.
- a compound of formula I can be converted to a corresponding lactam of formula II which itself can be converted by known means to a novel amino-acid of formula III and thence to a novel carbocyclic nucleoside of formula IV (Z is a purine, e.g. adenine or guanine).
- Z is a purine, e.g. adenine or guanine.
- the OH groups may be protected during preparation and/or use, e.g. as a 2,2-propylenedioxy group. Any susceptible group R may also be protected.
- the compounds of formula IV may be prepared by known means, e.g. as described above for Carbovir, from lactams of formula II. If desired, the OH groups may be retained or functionalised. Lactams of formula II may be prepared from cyclohexadienediols of formula I, e.g. by reaction with tosyl cyanide or chlorosulphonyl isocyanate.
- the illustrated aldehyde is prepared.
- a nucleophile may be used to introduce an alkyl or other group directly.
- nucleophile is methanol.
- Compounds of formula I may also be used to prepare organotransition metal (M) complexes of formula V, wherein L is a ligand and p an integer, specific examples are given as formulae Vi, Vii and Viii.
- M organotransition metal
- the attachment of a transition metal to the diene moiety adds an additional dimension to the synthetic potential of the dienediols. Transition metal complexes are undergoing rapid development as reagents for organic synthesis, and offer unique reactivities, frequently under exceptionally mild conditions and with high stereocontrol. A major problem in conventional approaches to these complexes is the limited access to homochiral material. The
- biotransformation The general attributes which make their use so attractive are the access they provide to optically pure compounds, chemically labile products, novel transformations, regio-controlled reactions, chemospecific transformations, substrate specificity (high specificity for a part of a substrate molecule and low specificity for the remainder), and new mutants with slightly differing specificities and thereby increasing the spectrum of substrates.
- Biotransformations can provide a ready source of many chiral starting materials, as above, but an
- the nutrient broth used purchased from Oxoid Ltd., Basingstoke, Hants, England, was reconstituted in
- the trace element solution used has the following composition; citric acid (100 g.1 -1 ), CaCl 2 .2H 2 O (4.38 g.1 -1 ), FeSO 4 .7H 2 O (8.0 g.1 -1 ), ZnSO 4 .5H 2 O (0.2 g.1 -1 ), CuSO 4 .5H 2 O (0.4 g.1 -1 ), CoCl 2 .6H 2 O (0.04 g.1 -1 ),
- a strain, HG5000, derived from a Pseudomonas testosteroni wild-type was isolated by enrichment culture in mineral salts medium (ASM) containing o-phthalic acid as sole source of carbon and energy. Mutagenesis of strain HG5000 with ethanemethanesulphonate, and recovery of surviving organisms on minimal salts medium containing 0.5% sodium succinate, gave strains which were further selected for an ability to grow in the presence of
- Halo 1 was found to accumulate cis-1,2- dihydroxy-4,5-dicarboxycyclohexa-3,5-diene when grown in the presence of o-phthalic acid when glucose was present as a source of carbon and energy.
- Mutant Halo 1 was grown overnight at 30°C with shaking in 2x250 ml of nutrient broth. The 500 ml of culture was then used to inoculate 4.5 litres of a medium containing succinic acid (4.72 g.1 -1 ), MgSO 4 .7H 2 O (0.25 g.1 -1 ), KH 2 PO 4 (3.0 g.1 -1 ), yeast extract (0.5 g.1 -1 ) trace element solution (10 ml 1 -1 ) and P2000 antifoam (1 ml 1 -1 ), adjusted to pH 6.8 with a 50% (v/v) aqueous ammonia solution (S.G. 880). This was stirred at 400 rpm, maintained at 30.5°C, and air was added at 2.5
- the volume of broth was kept constant by removing broth at the same rate as the feed solution was added.
- Product formation was monitored by HPLC and reached 70 mM after 25 hours, at which point the feed was stopped and the culture was left for a further 2 hours to enable residual substrate to be converted to product.
- the cells were harvested by centrifugation (10,000 g, 30 mins) and the supernatant was concentrated from 5 litres to 0.5 litres under vacuum by rotary evaporation at 45°C.
- the pH of the concentrate was then dropped to 2.0 by adding phosphoric acid, and it was repeatedly extracted with 5 volumes of ethyl acetate in the presence of anhydrous magnesium sulphate.
- the pH of the aqueous concentrate was readjusted to 2.0 between extractions, with further phosphoric acid.
- a strain, HG1001, derived from a Pseudomonas putida wild-type was isolated by enrichment culture in a minimal salts medium containing limonene as sole source of carbon and energy. It grows in the presence of p-cymene and metabolises this substrate via the p-cymene pathway
- a mutant strain HG1006 was derived from HG1001 following sequential selection for growth in the presence of two p-cymene analogues, p-toluic acid and
- Halo 2 was characterised as deficient in an active dihydrodiol dehydrogenase. This enzyme normally catalyses the oxidation, with NAD, of the p-cymene pathway intermediate 2R,3S-cis-dihydroxy-4-isopropyl- cyclohexa-4,6-diene-1-carboxylic acid.
- Mutant Halo 2 was grown overnight at 30°C with shaking in 2x250 ml of nutrient broth. The 500 ml of culture was then used to inoculate 4.5 litres of a medium containing glucose (10.0 g.1 -1 ), NH 4 SO 4 (1.0 g.1 -1 ), MgSO 4 .7H 2 O (0.25 g.1 -1 ), KH 2 PO 4 (3.0 g.1 -1 ), trace element solution (10 ml 1 -1 ) and P2000 antifoam (1 ml 1 -1 ), adjusted to pH 6.8 with a 50% (v/v) aqueous ammonia solution (S.G. 880) in distilled water.
- the cells were harvested by centrifugation (10,000 g, 30 mins) and the supernatant was concentrated from 5 litres to 0.5 litres under vacuum by rotary evaporation at 45°C.
- the pH of the concentrate was then dropped to 4.0 by adding phosphoric acid, and it was repeatedly extracted with 5 volumes of cold ethyl acetate.
- the pH of the aqueous concentrate was readjusted to 4.0 between extractions, with further phosphoric acid.
- the ethyl acetate fractions containing product were then evaporated to dryness to yield a crystalline powder which, following washing in cold ether, was found to be pure title
- a strain of Pseudomonas putida U was isolated by its ability to grow in the presence of benzoic acid as the sole source of carbon and energy. Another characteristic of the organism was an inability to grow in the presence of 2-fluorobenzoic acid even when benzoic acid was also present. Mutagenesis of this strain in the presence of NTG and recovery of surviving organisms on a minimal salts medium containing 0.5% sodium succinate gave strains which were further selected for their ability to grow in the presence of 2-fluorobenzoic acid as sole source of carbon and energy.
- Mutant Halo 3 was grown overnight at 30°C with shaking in 2x250 ml of nutrient broth. The 500 ml of culture was then used to inoculate 4.5 litres of a medium containing glucose (10.0 g.1 -1 ), NH 4 SO 4 (1.0 g.1 -1 ), MgSO 4 .7H 2 O (0.25 g.1 -1 ), KH 2 PO 4 (3.0 g.1 -1 ), trace element solution (10 ml 1 -1 ) and P2000 antifoam (1 ml 1 -1 ) adjusted to pH 6.8 with a 50% (v/v) aqueous ammonia solution (S.G. 880). This was stirred at 400 rpm, maintained at 30.5°C, and air was added at 2.5 1.min -1 . Sodium benzoate (5 mM) was then injected into the
- a pH of 6.8 was maintained by automatic titration with 30% (v/v) aqueous phosphoric acid and 50% (v/v) aqueous ammonia (S.G. 880). All solutions with the exception of the aqueous ammonia were sterilised by autoclaving at 121°C for 30 minutes prior to use. After 6 hours, the optical density of the broth measured at 600 nm in a 1 cm path length cell was 5-6.
- a pH of 6.8 was maintained by automatic titration with 50% (v/v) aqueous ammonia (S.G. 880), and dissolved oxygen tension was maintained at above 50% saturation by automatic adjustment of fermentor impeller speed.
- the volume of broth was kept constant by removing broth at the same rate as the feed solution was added.
- Product formation was monitored by HPLC and reached 28 mM after 24 hours, at which point the feed was stopped and the culture was left for a further 2 hours to enable residual substrate to be converted to product.
- the cells were harvested by centrifugation (10,000 g, 30 mins) and the supernatant was concentrated from 5 litres to 0.5 litres under vacuum by rotary evaporation at 45°C.
- the pH of the concentrate was then dropped to 2.2 by adding phosphoric acid, and it was repeatedly extracted with 5 volumes of cold ethyl acetate.
- the pH of the aqueous concentrate was readjusted to 2.2 between extractions, with further phosphoric acid.
- the ethyl acetate fractions containing product were then evaporated to dryness to yield a crystalline powder which, following washing in cold ether, was found to be pure title
- the iron carbonyl complex of formula Vi is prepared by reacting the corresponding uncomplexed compound with Fe(CO) 9 .
- the complex is reacted with (Ph) 3 C-BF 4 and NH 4 PF 6 , and then with NaBH 4 , to remove one methoxy group; the product is reacted with CF 3 COOH/NH 4 PF 6 , to remove the other methoxy group (20% yield).
- the product is then reacted with NaCH (COOMe) 2 to give the compound of formula Vli stereospecifically, in 72% yield.
