- A process for the preparation of [3 - [(2 R) - [(1 R) - 1 - [3, 5 - di (trifluoromethyl) phenyl] ethoxy] - 3 (S)- (4 - fluorophenyl) morpholine - 4 - yl] methyl] - 5 - oxo - 4, 5 - dihydro - [1, 2, 4] - triazole - 1 - yl] phosphine acid animal pen ester new method
-
The invention relates to a new method for preparing fosaprepitant intermediate, namely, [3-[(2R)-[(1R)-1-(3, 5-bi (trifluoromethyl) phenyl] ethyoxyl]-3 (S)-(4-fluorophenyl) morpholine 4-group] methyl]-5-oxo-4, 5-dihydro-[1, 2, 4]-triazole-1-group] phosphonic acid-benzyl ester. The compound is an important medicine intermediate, and is used for preparing antiemetic drug fosaprepitant. The new method comprises the steps of: enabling newly prepared phosphorylation agent dibenzyl phosphorus oxychloride and aprepitant to have reaction in organic solvent under the action of steric hindrance alkali, treating the product with methyl alcohol to obtain the fosaprepitant intermediate. The method is simple in operation and low in cost, thus being more suitable for industrial production.

- Reaction of chlorides of phosphoric, sulfonic, and carboxylic acids on solid potassium carbonate surface under PTC circumstances
-
Simple syntheses of phosphoric (4) and carboxylic (6) acid anhydrides have been elaborated by means of solid potassium carbonate in phase-transfer catalytic acylation. Behavior of various acid chlorides, phosphoric (1), sulfonic (2), and carboxylic (8), have also been studied toward potassium carbonate in the presence of lipophilic quaternary ammonium salt.

- Thiosugar nucleotide analogs: Synthesis of 5′-(2,3,4-tri-O-acetyl-6-S-acetyl-6-thio-α-D-galactopyranosyl diphosphate)
-
The synthesis of a novel analog of uridine diphosphate galactose (UDP-Gal) is described. A sulfur atom was inserted into the 6-position of galactose to give uridine 5′-(2,3,4-tri-O-acetyl-6-S-acetyl-6-thio-α-D-galactopyranosyl diphosphate). This peracetylated thiol analogue of UDP-Gal has been synthesized in nine steps starting from methyl α-D-galactopyranoside in an overall yield of 3%.

- Selective phosphorylation on primary alcohols of unprotected polyols
-
The triad tribenzylphosphite-iodine-pyridine offers a general selective method for phosphorylation reactions of primary alcohols of unprotected α-diols and polyols. A mechanistic study by 31P NMR allowed to evidence the formation, from iododibenzyl phosphate and pyridine, of a very reactive pyridinium salt intermediate. This analysis shows that pyridine behaves as a covalent catalyst like DMAP in acylation reactions from acylchloride. Due to its steric hindrance and high reactivity, this species appears to be the efficient selective phosphorylation reagent but leads to dibenzylphosphoric esters. Under mild conditions, the cleavage of benzyl groups gives monoester phosphoric acid.

- Stereoselective synthesis of inositol mono, bis and trisphosphate analogue from 6-deoxy-D-inositol precursors
-
The synthesis of opticaly pure deoxy-myo-inositol mono, bis and trisphosphate analogues is described from 4-O-benzyl-2,3-di-O- cyclohexylidene-6-deoxy-myo-inositol and corresponding 1,5 epimer chiro- inositol. These precursors, which derive from galactose, are used to accede to a variety of cyclitol intermediates employing protection/deprotection sequence. The phosphorylation procedure was performed to produce free and original substituted phosphate derivatives aimed to be incorporated through the lipidic cell membrane for in vivo evaluation.
