Crystal structure of meso-3,3 ‘-(1,4-ohenylene)bis(2-phenyl-2,3,5,6-tetrahydro-4H-1,3-thiazm-4-one)

The crystal structure of the title compound – meso-C26H24N2O2S2 with two stereocenters – has half the molecule in the asymmetric unit with the other half generated by a crystallographic center of inversion. The thiazine ring is in a conformation that is between half-chair and envelope [theta = 52.51 (17)degrees]. The phenyl ring on the 2-carbon atom of the thiazine ring is pseudo-axial. The central phenyl ring of the molecule is close to orthogonal to the phenyl rings on either side with an angle of 76.85 (11)degrees between those planes. In the crystal, pairwise, weak C-H center dot center dot center dot O hydrogen bonds between the central phenyl ring and the oxygen atoms of neighboring molecules result in continuous strips propagating along the a-axis direction. Hydrophobic interactions of the C-H center dot center dot center dot pi type are also observed.

Oxicams, a Class of Nonsteroidal Anti-inflammatory Drugs and Beyond

Oxicams are a class of nonsteroidal anti-inflammatory drugs (NSAIDs) structurally related to the enolic acid class of 4-hydroxy-1,2-benzothiazine carboxamides. They are used clinically to treat both acute and chronic inflammation by inhibiting the activity of the two cyclooxygenase (COX) isoforms, COX-1 and COX-2. Oxicams are structurally distinct from all other NSAIDs, exhibiting a novel binding pose in the COX active site. The 4-hydroxyl group on the thiazine ring partners with Ser-530 via hydrogen bonding while two coordinated water molecules mediate a polar interaction between the oxicam and COX. The rotation of Leu-531 in the complex opens a new pocket, which is not used for binding other NSAIDs to the enzyme. This structure provides the basis for understanding documented structure-activity relationships within the oxicam class. In addition, from the oxicam template, a series of potent microsomal prostaglandin E synthase-1 (mPGES-1) inhibitors represents a new direction for drug development. Here, we review the major route of oxicam synthesis and structure-activity for COX inhibition, as well as recent advances in oxicam-mediated mPGES-1 inhibition.

Sorption of Methylene Blue on Polystyrene/Bentonite Film Composites

The method of mechanochemical dispersion of bentonite in a polystyrene solution was used to modify the polymer and obtain film materials with improved sorption characteristics with respect to the methylene blue (MB) thiazine dye. It is found that the kinetics of the dye sorption are described by the pseudo-first-order equation. The sorption equilibrium is described by the Langmuir isotherm. The values of the limiting sorption capacity and specific surface area of the composite are determined. It is shown that the sorption efficiency of the dye on the PS/bentonite composite increases tenfold as compared with the non-modified sorbent; the extraction rate increases from 10 to 90%. The method of IR spectroscopy is used to show that MB sorption on polystyrene and the PS/bentonite composite is accompanied by electrostatic and donor-acceptor interactions of the reaction sites of MB with the hydroxyl-containing groups of the composite.

General synthetic approach towards annelated 3a,6-epoxyisoindoles by tandem acylation/IMDAF reaction of furylazaheterocycles. Scope and limitations

An efficient and versatile one-pot synthesis of 3,6a-epoxyisoindoles annelated with oxazine, oxazole, thiazine, thiazole, pyrimidine fragments and with their benzoannelated analogues is presented. The method is based on tandem N-acylation/intramolecular cycloaddition (the intramolecular Diels-Alder reaction of furan, IMDAF) reaction between alpha,beta-unsaturated acid anhydrides and alpha-furyl substituted azaheterocycles. The latter can be easily prepared by condensation of diverse furfurals and 1,2- or 1,3-N,X-binucleophiles (aminoalcohols, aminothiols, diamines). The observed IMDAF reaction is stereo-selective: exo-adducts are formed exclusively with large prevalence of one of the diastereoisomers. In most cases, the condensation/N-acylation/IMDAF reaction sequence may be carried out via a one-pot domino protocol. The scope and limitations of the proposed approach are thoroughly investigated. The obtained Diels-Alder adducts are attractive and useful substrates for further transformations. Fused isoindoles can be prepared from them in one-step by aromatization of the 7-oxabicyclo[2.2.1]heptene ring. Other transformations, including halogenation, ring cleavage, and Wagner-Meerwein skeletal rearrangement, are also demonstrated. The spatial structures of the obtained compounds have been established by X-ray diffraction analyses. (C) 2014 Elsevier Ltd. All rights reserved.

A facile and rapid entry towards assembly of novel imidazo[2,1-b][1,3] thiazinyl-alpha-aminophosphonate scaffolds through a onepot, sequential reaction of 2-amino-4H-1,3-thiazine-3-one, dialdehydes, isocyanides, aromatic amines and dialkyl/aryl phosphites is demonstrated. Successive sequencing of Groebke-Blackburn-Bienayme (GBB) reaction with Kabachnik Field’s reaction results in the efficient formation of novel bis-heterocyclic frameworks. The highlights of the present protocol include survival of the aldehydic group post GBB without any protection. Additionally, simplicity of execution excluding both solvent and catalyst, cheap reagents, excellent functional group tolerance under minutes of microwave irradiation justify it to be a green protocol.

An Efficient One-Pot Synthesis of Benzo[1,4]Thiazines, Benzo[1,3]Thiazoles and Benzo[1,5] Thiazepines

Background: One-pot reactions have gained considerable and wide range of interests in the field of chemistry due to their simplicity and economy. Comparing to the step-by-step reactions that involve the formation of individual bonds for a given target product, the greatest attribute of one-pot reactions, is the formation of several bonds in one-pot operation without intermediate isolation, reaction condition changing and further reagents adding. Objective: We developed an one-pot, rapid, simple and eco-friendly synthetic strategy for benzothiazines, benzothiazoles and benzothiazpines through the interaction of o-aminothiophenol with ketones, nitriles and chalcones, respectively. Method: A mixture of o-aminothiophenol ketones, nitriles and chalcones was refluxed or stirred at room temperature in glacial acetic acid containing a catalytic amount of concentrated H2SO4 for 3h. Then, the resulting precipitate was collected by filtration, washed with water and crystallized from the appropriate solvent. Results: The interaction of o-aminothiophenol with aromatic and aliphatic ketones containing active alpha-hydrogens afforded the corresponding 2H-benzo[1,4] thiazines and 4H-benzo[1,4] thiazines, respectively. Similarly, the cyclic ketones afforded the corresponding tricyclic compounds. Treatment of o-aminothiophenol with nitriles under the same reaction condition gave benzo[1,3] thiazoles. Further, cyclocondensation with chalcones under the same reaction condition at room temperature yielded the corresponding benzo[1,5] thiazepines. The reaction mechanism was investigated and the structures of all new compounds were elucidated using spectral analysis. Conclusion: An efficient, simple and environmentally friendly synthesis of benzothiazines, benzothiazoles and benzothiazepines in one-pot synthesis has been developed. With this catalytic reaction, a very cheap sulfuric acid was used as a catalyst.
