Definitions
- the invention relates to a process for the synthesis of difluorinated gem compounds. It applies more particularly, but not exclusively, to the preparation of glycoconjugate compounds and C-glycosides in particular for the manufacture of antitumor, antiviral, hypoglycemic, anti-inflammatory drugs or for immunology, cosmetology and the preparation of glycopeptide analogues of antifreeze molecules.
- These compounds are inhibitors of phosphatase enzymes which are involved in the transduction of intracellular signals.
- glycoconjugate compounds are studied with attention. These are compounds formed from the conjugation between a sugar and another compound (aglycone) such as an amino acid (glycoprotein, glycopeptide), a lipid (glycolipid), a steroid or a triterpene, an alkaloid, a ketone ... Indeed, the latter, with inter alia glycoproteins and glycolipids which are constituents of cell membranes, are compounds widely involved in many biochemical processes such as intercellular recognition or regulation of cell growth. For this reason, glycoconjugate compounds are of considerable therapeutic importance and find applications as antitumor or antiviral. However, these compounds, due to the presence of an osidic bond (bond involving the oxygen called in the anomeric position) are fragile with respect to several enzymatic systems including the protease enzymes and the hydrolase enzymes.
- the invention therefore more particularly aims to solve these drawbacks.
- R 1 is a group comprising an alkyl chain substituted by at least one ineimine, amide or acid function,
- R is a hydrogen atom H or a free or protected alcohol function
- R 3 is in particular a group H, CH 3 , CH 2 OH, CH 2 -OGP where GP is a protective group such as an alkyl or benzyl group ( Bn), trimethylsilyl
- TMS tert-butyldimethylsilyl
- TDPS tert-butyldiphenylsilyl
- Ac acetate
- Y, Y ', Y are independent groups
- R ', R "- H, alkyl, allyl, Bn, tosylate (Ts), C ( 0) -alkyl,
- R '" H, alkyl, Ac.
- this compound of general formula I can be prepared by a reaction between a lactone of general formula II: where R 3 is in particular a group H, CH 3 , CH 2 -OGP where GP is a protective group such as an alkyl, benzyl (Bn), trimethylsilyl (TMS), tert-butyldimethylsilyl (TBDMS), tert-butyldiphenylsilyl ( TBDPS), acetate (Ac) ...,
- R '"- H alkyl, Ac.
- at least one halogen derivative of general formula XCF 2 C0 2 R, where X is a halogen, in the presence of zinc or a lanthanide derivative and R alkyl, aryl .. .
- Said lanthanide derivative may for example be the samarium diiodide Sml 2 .
- said process could use zinc in combination with titanocene.
- R 5 and R H or a functionalized or non functionalized group such as a functionalized carbon chain carrying inter alia an amino, amino acid, aminoester function, a peptide chain, a protein, a carbohydrate, a steroid or a triterpene, an alkaloid, a lignan or compounds of pharmacological interest ...
- the gem-difluorinated compounds may more precisely have the general formula IVa and IVb:
- R 5 , R 6 , R 7 and. R 9 H or a functionalized group or not such as a functionalized carbon chain carrying inter alia an amino, amino acid, amino ester function, a peptide chain, a protein, a carbohydrate, a steroid or a triterpene, an alkaloid, a lignan or compounds of pharmacological interest.
- One of the intermediate compounds obtained for obtaining compounds of formula I could be a compound of general formula V comprising an ester function: FR2003 / 002330
- R may be a group such as an alkyl, aryl, allyl group, this group being functionalized or not.
- This ester function -C0 2 R 4 may also be reduced in alcohol function, for example by sodium tetraborohydride (NaBH 4 ) or lithium aluminum tetrahydride (LiAlH 4 ) to give C-glycoside compounds of general formula VII:
- compounds of general formula I can be obtained by coupling a sugar derivative with an amino, for example an amino acid or a peptide.
- the CF 2 group is particularly resistant to biochemical degradation processes and therefore allows the synthesis of non-hydrolysable structures.
- compositions thus obtained may also contain preservatives.
- Other active ingredients can be added to these compositions.
