Definitions
- the present invention relates to a method for the production of statins known as HMG-CoA reductase inhibitors.
- statins known as HMG-CoA reductase inhibitors.
- Statins are a well-known class of drugs that inhibit the enzyme hydroxymethylglutaryl (HMG) coA reductase.
- the active ingredients are widely used, especially as a cholesterol-lowering agent in the blood.
- Known statins are, for example, cerivastatin, fluvastatin, itavastatin, BMY22089, rosuvastatin, glenvastatin and atorvastatin. Synthetic pathways for the statins are known and described in a variety of publications.
- Statins are in principle composed of an aromatic, heterocyclic or an aromatic-heterocyclic, substituted or unsubstituted, mono-, di- or polycyclic ring system to which the so-called statin side chain hangs either in the open-chain form or in the lactone form
- statin is the ring system described above, ie the rest of the statin.
- statin as used in this description also includes the pharmaceutically acceptable salts, hydrates, solvates, esters and ethers of the statins described in the prior art.
- statins Of crucial importance to the efficacy of the statins is the spatial arrangement of the hydroxyl groups in the statin side chain as indicated in the above formula. Economically, it makes sense in the synthesis of statins to determine the stereochemistry already in a very early step and the next steps to obtain the stereochemistry, ie stereoselectively, to achieve the highest possible yields of the To obtain final product (products with a different stereochemistry must be separated).
- Ts represents a tosyl protecting group
- statins which are economical and by means of which the statins can be prepared simply, in high yield and using fewer process steps.
- statin synthesis which is based on the early experiments, as described, for example, in the publication J. Org. Chem., Vol. 49, No. 21, 1984, 3994-4003, but there is little prospect which provides statins with the desired statin side chain in good yield and high optical purity when synthesized via a lactol intermediate.
- Some of the intermediates are known from the literature, others of the intermediates are new compounds. According to the invention, a process has also been found with which these intermediates can be prepared simply and in high yield.
- the invention thus relates to a method for producing a statin, comprising the following step: a) reduction of a compound of formula II
- 5 1 represents a hydrogen atom or a hydroxyl-protecting group
- S 5 2 and S 3 independently of one another represent hydroxyl-protecting groups, where S 2 and S 3 together may be a bridging hydroxyl-protecting group, and R 1 represents a hydrogen atom or a carboxyl-protecting group,
- S 4 represents a hydrogen atom or a hydroxyl-protecting group.
- the reduction may be carried out, for example, with cooling (e.g., -78 ° C) in ethanol by means of DIBALH (diisobutylaluminum hydride).
- DIBALH diisobutylaluminum hydride
- Residual S 1 represents a hydrogen atom or a hydroxyl-protecting group.
- Hydroxyl protecting groups are known in the art and may be referred to, for example, the general reference Protective Groups in Organic Synthesis, Theodora W. Greene and Peter GM Wuts, 2nd Edition, John Wiley & Sons to get expelled. Suitable hydroxyl-protecting groups are also mentioned, for example, in WO 03/004450, to which reference is made in this respect.
- Preference according to the invention is given to hydroxyl-protecting groups having 4 to 10 carbon atoms and optionally 1 to 3 heteroatoms. Particularly preferably, the hydroxyl-protecting group contains one silicon atom, 5 to 10 carbon atoms and no further heteroatoms.
- the hydroxyl-protecting group S 1 is particularly preferably a trimethylsilyl, triisopropylsilyl, triethylsilyl, tert-butyldimethylsilyl, di-tert-butylmethylsilyl, tert-butyldiphenylsilyl, triphenylsilyl, diphenylmethylsilyl or tris (trimethylsilyl) protective group.
- the hydroxyl protecting group S 1 is a tert-butyldiphenylsilyl group.
- protective groups of the general formula ROC (O) - and RC (O) - where R is an alkyl group, in particular a C 1 -C 6 -alkyl group, such as a tert-butyl group, or an aryl group, in particular a C 5 -C 10 -
- Aryl group such as a phenyl group, or an alkyl-aryl group, in particular a C 1 -C 6 - alkyl-C 5 -C 10 -aryl group represents.
- the radicals S 2 and S 3 may be conventional hydroxyl-protecting groups and the same hydroxyl-protecting groups as mentioned above in connection with the hydroxyl-protecting group S 1 may be used. Again, reference may be made to the standard work Protective Groups in Organic Synthesis, Theodora W. Greene and Peter GM Wuts, 2nd edition, John Wiley & Sons. Preferably, S 2 and S 3 form but together a bridging hydroxyl protecting group as it is known in principle. Examples of suitable bridging hydroxyl-protecting groups are disclosed in WO 03/004450, to which reference is made. Particularly preferably, the protective groups S 2 and S 3 together form an isopropylidene protective group.
- R 1 represents a hydrogen atom or a carboxyl protecting group.
- Carboxyl protecting groups are known to the person skilled in the art and are described, for example, in Protective Groups in Organic Synthesis, Theodora W. Greene and Peter GM Wuts, 2nd edition, John Wiley & Sons.
- R 1 may be a hydrogen atom, a d.
- alkyl or aryl Cs.i O which are optionally substituted with one or more groups independently selected from halogen atoms, C 1 -C 0 - - 3 alkyl, C 5 -C 10 alkoxy groups, heterocycles from 0 to 10 carbon atoms, preferably 1 to 5 carbon atoms, and 1 to 10 heteroatoms, preferably 1 to 5 heteroatoms selected from sulfur, nitrogen and oxygen atoms, and functional groups.
- R 1 is a d. 8 alkyl or C 5 . 10 -aryl radical, which are optionally substituted by one or more radicals which are independently selected from halogen atoms, tetrazolyl, Ci. 8 alkoxy, nitro and cyano groups.
- the radical R 1 is particularly preferably a Ci. 8 -alkyl, in particular a C ⁇ -Alkytrest, wherein an ethyl radical is most preferred, especially when the radical S 1 is a tert-butyldiphenylsilyl group.
- the compound of formula VI can be readily converted to the lactol I-a desired as an intermediate for statin synthesis:
- S 4 represents a hydrogen atom or a hydroxyl-protecting group as defined above for S 1 .
- statins which are important intermediates in the production of statins.
- the radical S 1 is as defined above.
- W O or -OS 4 .
- Formula I is a Wittig reagent or a Homer-Wittig reagent, which can later undergo a Wittig reaction or a Horner-Wittig reaction with the correspondingly functionalized ring system St of the statin.
- the ring system St, with which the compound of the formula I is converted to the statin, should in this case preferably carry an aldehyde group at the coupling site.
- the radicals R 3 , R 4 and R 5 are preferably the usual groups which complete a Wittig residue or a Horner-Wittig residue, so that the compounds can undergo a Wittig reaction or a Horner-Wittig reaction.
- the radical R 3 thus usually denotes a C 5 - to Cio-aryl radical which is optionally substituted by one or two C 1 -C 4 - alkyl radicals and / or halogen atoms, a C 1 -C 4 -alkyl radical or a C 5 -C 10 -cycloalkyl radical , in particular a phenyl radical, an n-C 1 -C 4 -alkyl radical or a cyclohexyl radical.
- the phenyl radical is preferably unsubstituted.
- the phenyl radical is preferably also substituted by one or two nC r C 4 -alkyl radicals or chlorine atoms.
- the radical R 4 is preferably a C 1 -C 4 -alkyl radical, in particular an n-C 1 -C 4 -alkyl radical, particularly preferably an ethyl group
- the radical R 5 is preferably a C 5 -C 10 -aryl radical or a C 1 -C 6 -alkyl radical, in particular a C 5 -C 10 aryl radical or a C 1 -C 4 alkyl group, more preferably a phenyl, methyl or ethyl group.
- these radicals are not particularly limited, provided that the later required Wittig (or Horner-Wittig) reaction can be carried out with them.
- the ring system St with which the compound of the formula I is converted to the corresponding statin, should have a corresponding functional group, so that a Wittig reaction or a Horner-Wittig Reaction can be carried out.
- the Wittig reaction and the Horner-Wittig reaction are known implementations, and reference can be made to relevant organic chemistry textbooks, eg, March, Advanced Organic Chemistry, 4th Edition, 1992, John Wiley and Sons.
- the radical R 2 represents a halogen atom, in particular a chlorine, bromine or iodine atom, a cyanide group (-C ⁇ N), a -CH 2 NH 2 group, a group SO 2 -R 6 or a leaving group.
- a halogen atom in particular a chlorine, bromine or iodine atom, a cyanide group (-C ⁇ N), a -CH 2 NH 2 group, a group SO 2 -R 6 or a leaving group.
- the compound of the formula I is, in particular, an intermediate for preparing a compound of the formula I, in which R 2 represents a -CH 2 NH 2 group.
- the compound of formula I in which R 2 represents a -CH 2 NH 2 group is a particularly preferred intermediate suitable for the preparation of atorvastatin.
