Quinolonecarboxylic Acids. 2. Synthesis and Antibacterial Evaluation of 7-Oxo-2,3-dihydro-7H-pyrido<1,2,3-de><1,4>benzothiazine-6-carboxylic Acids

A series of pyridobenzothiazine acid derivatives was synthesized and their in vitro antibacterial activity was evaluated.The 1,4-benzothiazine intermediates, which by Gould-Jacobs quinoline synthesis produced pyridobenzothiazine acids, were prepared by hydrolytic basic cleavage of substituted 2-aminobenzothiazoles and successive cyclocondensation with 1-bromo-2-chloroethane or alternatively with monochloroacetic acid, hence reduction by LiAlH4.The pyridobenzothiazine acids 10c, 30, and 31 show potent antibacterial activities against Gram-positive and Gram-negative pathogens.Structure-activity relationships are discussed.The compound 9-fluoro-10-(4-methyl-1-piperazinyl)-7-oxo-2,3-dihydro-7H-pyrido<1,2,3-de><1,4>benzothiazine-6-carboxylic acid (31) (MF-934) has been found to possess, together with the antibacterial activity, a weak acute toxicity and interesting pharmacokinetic characteristics in several animal species (rat, dog, monkey, man).

Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 3080-99-7, Name is 3,4-Dihydro-2H-benzo[b][1,4]thiazine. In a document type is Article, introducing its new discovery., 3080-99-7

Biotransformation of organic sulfides. Part 12. Conversion of heterocyclic sulfides to chiral sulfoxides by Helminthosporium sp. NRRL 4671 and Mortierella isabellina ATCC 42613

The enantioselective oxidation of a series of heterocyclic prochiral sulfides to chiral sulfoxides has been examined using the fungal biocatalysts Helminthosporium species NRRL 4671 and Mortierella isabellina ATCC 42613. Methylthiofuranyl and -thiophenyl substrates gave (S)-configuration products in low to moderate enantiomeric purity on biotransformation with H. species, but pyridyl sulfides with the nitrogen atom located at an optimal distance of 8-10 A from the sulfur centre gave (S) sulfoxides of high enantiomeric purity. The biotransformation of appropriately substituted benzothiane substrates by M. isabellina also gave products of high enantiomeric purity, but with (R) configuration at sulfur. The acceptability of the substrate and the configuration of sulfur oxidation by both H. species and M. isabellina for the range of substrates examined were found to be consistent with predictions based on cubic space models for these oxidations.

Access to Phenothiazine Derivatives via Iodide-Mediated Oxidative Three-Component Annulation Reaction

Herein, a new iodide-mediated three-component annulation reaction of secondary anilines, cyclohexanones, and elemental sulfur is demonstrated, which allows access to various phenothiazines with the merits of formation of multiple chemical bonds in one single operation, high step and atom efficiency, readily available feedstocks and catalyst system, and good substrate and functional group compatibility. The developed chemistry capable of constructing novel phenothiazines with structural diversity offers a significant basis for further applications.

Eliminative Ring Fission of 4-Acyl-2,3-dihydro-4H-1,4-benzothiazines

The behavior of 4-acyl-2,3-dihydro-1,4-benzothiazines 1-11 upon treatment with lithium diisopropylamide (LDA) in THF at -78 deg C has been examined.Very marked differences have been observed.Whereas unsubstituted and monosubstituted derivatives (1-4) readily undergo “eliminative ring fission”, providing 2-(alkylthio)phenylenamides 12, 2-aminophenyl vinyl sulfides 16, and 3-acylbenzothiazolines 13, 2,3-disubstituted derivatives (5-7) do not react at all.The relationship between structural features of the above-mentioned dihydrobenzothiazines and their reactivity is considered.Lithium ion plays a fundamental role in providing activation for the ring-opening reaction.

Selective N-alkylation of arylamines with alkyl chloride in ionic liquids: Scope and applications

An efficient N-selective alkylation of primary aromatic amines in molten quaternary ammonium salts, as the solvent, under relatively mild and base-free conditions is presented. On the basis of the Kamlet-Taft parameters and the nucleophilicity of the IL (ionic liquid) anions, the influence of the ionic liquid was evaluated. This protocol was validated on a larger multigram scale and with the syntheses of bioactive heterocycles (e.g., 1,4-benzothiazine and quinoxalines) and new efficient MALDI matrixes. Copyright
