Preparation method of moxifloxacin

The invention provides a preparation method of moxifloxacin, which comprises the following steps: taking 1-cyclopropyl-6, 7-difluoro-8-methoxy-4-oxo-1, 4-dihydro-3-quinolinecarboxylic acid and (S, S)-2, 8-diazabicyclo[4.3. 0] nonane as raw materials, in an organic solvent, in the presence of an acid-binding agent, and carrying out condensation reaction by taking the tri-coordinated boride cation-chloroaluminate ionic liquid as a catalyst to prepare moxifloxacin. The structural formula of the tri-coordinated boride cation-chloroaluminate ionic liquid is BX2L, X is a halogen atom, and L is selected from 4-picoline (4-pic), imidazole (mim) and dimethylacetamide (DMA) ligands. The preparation method of moxifloxacin has the advantages of simple reaction steps, high yield, high product purity, mild conditions and easiness in industrial production.

Nano-Fe3 O4@ZrO2-SO3 H as highly efficient recyclable catalyst for the green synthesis of fluoroquinolones

Nano-Fe3 O4 @ZrO2-SO3 H (n-FZSA), was utilized as a magnetic catalyst for the synthesis of various fluoroquinolone compounds. These compounds were prepared by the direct amination of 7-halo-6-fluoroquinolone-3-carboxylic acids with piperazine derivatives and (4aR,7aR)-octahydro-1H-pyrrolo[3,4-b] pyridine in water. The results showed that n-FZSA exhibited high catalytic activity towards the synthesis of fluoroquinolone derivatives, giving the desired products in high yields. Furthermore, the catalyst was recyclable and could be used at least seven times without any discernible loss in its catalytic activity. Overall, this new catalytic method for the synthesis of fluoroquinolone derivatives provides rapid access to the desired compounds in refluxing water following a simple work-up procedure, and avoids the use of organic solvents.

IR, FT-ICR-MS studies on (1′S, 6′S)-1-cyclopropyl-7-(2,8- diazabicyclo[4.3.0] non-8-yl)-6-fluoro-8-methoxy-4-oxo-1,4-dihydroquinoline-3- carboxylic acid hydrochloride salt

The infrared spectra of (1′S, 6′S)-1-cyclopropyl-7-(2,8- diazabicyclo[4.3.0] non-8-yl)-6-fluoro-8-methoxy-4-oxo-1,4-dihydroquinoline-3- carboxylic acid hydrochloride salt (CLF-HCl) were studied and compared with free base. Their fragmentation pathways were investigated using tandem mass spectrometric (MS/MS) techniques on Fourier-transform ion cyclotron resonance spectrum, and many characteristic fragment ions were found.
