Definitions
- the present invention relates to a new process for the preparation of 1,6: 2,3-dianhydro- ⁇ -D-mannopyranose, hereinafter referred to as "Cerny epoxide” or “compound (I)” and having the following formula , in which the bold lines represent bonds located above the pyranosic cycle:
- Compound 1 is obtained from levoglucosan 2 (or 1,6-anhydro- ⁇ -D-glucopyranose), as shown below (M. Cerny et al., Collect, Czech Chem., 1961, vol. 26, pp. 2542-2550):
- the ditosylated derivative 3 (1,6-anhydro-2,4-di-O-tosyl- ⁇ -D-glucopyranose) is obtained selectively (80%). The remaining 20% is essentially composed of the tritosyl derivative. The overall yield for the conversion of compound 2 to compound 1 is 55%.
- this sequence includes, inter alia, the difficulty of selectively hydrolysing the 3,4-anhydro function during the first step.
- the hydroxyl at the 4-position of the monotosylated derivative 8 is then protected by a trityl (Tr) group in order to prevent the migration of the epoxide during cyclization in the presence of sodium ethoxide (EtONa).
- Cerny epoxide (I) may be obtained from the derivative 8 in the presence of Amberlite resin IRA 400 / OH ".
- Amberlite resin IRA 400 / OH the resin that results in the migration of the 3,4-epoxide in the 3,4-position and the formation of the derivative H (1,6: 3,4-dianhydro- ⁇ -D-altropyranose), thus remaining the difficulty of selectively obtaining the compound (I). 8 is also difficult to obtain selectively, as mentioned above.
- the three access routes described above for the preparation of the Cerny epoxide (I) have respectively 10, 8 and 9 steps from D-glucose (using, for obtaining levoglucosan 2 , cyclization in acidic medium, which is the described pathway with the best yield) and have overall yield, respectively for lanes 1, 2 and 3, 0.5%, 10% and 13%.
- the Cerny epoxide can be formed from a precursor previously cyclized between positions 1 and 6, or an N-1 precursor of the Cerny epoxide acetylated at position 4 can be obtained at 5%, in several steps from 1, 3,4-tri-O-acetyl-2,6-di-O-tosyl glucose subjected to alumina, irradiation under midroondes and per-O-acetylation.
- the method according to the invention comprises the steps shown below in Scheme 1.
- the subject of the invention is thus a process for the preparation of the compound (I), characterized in that it comprises a step of cyclisation of the compound C in an alcohol / alkoxide mixture, under anhydrous conditions.
- R represents an alkyl group having from 1 to 4 carbon atoms, for example a methyl group
- R ' represents an activating agent, for example a tosyl, mesyl or benzenesulphonyl group.
- Alkyl a saturated, linear or branched aliphatic group, for example a methyl group
- Alcohol a compound of formula alkyl-OH, in which the alkyl group is as defined above and comprises from 1 to 3 carbon atoms, for example methanol;
- Alkoxide the conjugated base of the alcohol as defined above, that is to say the anion corresponding to the formula alkyl-O " , bearing an alkali metal counterion such as sodium ;
- alcohol / alcoholate mixture a mixture of an alcohol with the corresponding alcoholate, for example a methanol / sodium methanolate mixture (CH 3 OH / CH 3 ONa);
- Activating agent an agent allowing the departure group leaving the group -OR 'and promoting the cyclization reaction between the positions 1 and 6 of the compound C_, for example a tosyl, mesyl, benzenesulphonyl or benzenesulphonyl derivative group, such as a p-halogenobenzylsulfonyl halide.
- the cyclization of compound C is advantageously carried out using 2 to 3 equivalents of alkoxide (expressed relative to the molar amount of compound C), preferably 2.2 equivalents.
- the subject of the invention is also a process for preparing compound (I), characterized in that it comprises a step of acylating compound B (in which R 'is as defined above), making it possible to obtain the compound C, followed by a step of cyclization of the compound C in an alcohol / alcoholate mixture, as defined above.
- the acylation step of the compound B is carried out using an acylating agent allowing the introduction of the R-CO- groups in the compound C 2; such an acylating agent may for example consist of an acid anhydride, such as acetic anhydride, or an acyl chloride.
- an acylating agent may for example consist of an acid anhydride, such as acetic anhydride, or an acyl chloride.
- at least three equivalents of acylating agent are used relative to compound B.
- the compound C is such that R represents a methyl group.
- the acylation reaction of compound B consists of an acetylation reaction, carried out for example with acetic anhydride, in a solvent such as dichloromethane.
- the subject of the invention is also a process for the preparation of the compound (I), characterized in that it comprises a step of activating the compound A (D-glucose), making it possible to obtain the compound B, and then a step d acylation of compound B, followed by a step of cyclizing compound C, obtained at the end of the preceding stage, in an alcohol / alkoxide mixture under anhydrous conditions.
- the activation step of compound A can be carried out using an activating agent as defined above.
- tosyl chloride is advantageously used in a solvent such as pyridine.
- the process according to the invention makes it possible to selectively obtain the compound (I) (1, 6: 2,3-dianhydro- ⁇ -D-mannopyranose) in three stages from D-glucose, in particular because of the low basicity of the medium during the cyclization reaction of intermediate C, anhydrous reaction conditions and the number of equivalents of sodium methanolate used.
- the compound (I) is obtained, according to the process of the invention, with a selectivity of at least 90% from intermediate C.
- the chemical yield calculated on isolated product that is to say after the various washing steps, filtration, removal of solvent required for its isolation, as is conventional to implement them in organic chemistry, is at least 60%.
- Transformation reactions of D-glucose to Intermediate B and subsequent formation of Intermediate C from Compound B have a chemical yield of at least 50% and 80%, respectively.
- Step 1 Preparation of compound B '(2,6-di-O-tosyl-glucopyranose)
- the rate of progress of the reaction is monitored by TLC (eluent CH 2 Cl 2 ZMeOH 9/1 VA / for the quantification of di- and tritosyl derivatives, eluent CHCl 3 / EtOH / AcOH / H 2 O 48/40/8/4 V / V for monitoring D-glucose) and HPLC under customary conditions. It is concentrated by distillation at 45-50 ° C. under vacuum. When the medium thickens and the residual volume is about 1000 ml, 750 ml of demineralized water are charged, the mixture is homogenized and then about 750 ml of the mixture is distilled at a temperature of about 45-50 ° C. about 20 mmHg (solvent exchange operation by distillation).

- 1000 ml of dichloromethane are added and the mixture is homogenized with stirring.
- 1000 ml of demineralized water and 100 ml of hydrochloric acid are successively introduced, the mixture is stirred for a further 30 minutes and, after decantation, the acidic aqueous phase is removed.
- a solution consisting of 1000 ml of demineralised water and 100 g of NaCl is introduced into the preceding mixture. The mixture is stirred for a further 30 minutes, decanted and the aqueous phase removed.
- step 1 The yield of step 1 is 64%.
- Step 2 Preparation of compound C (or 1,3,4-tri-O-acetyl-2,6-di-O-tosyl glucose)
