Organo-nanocatalysis: An emergent green methodology for construction of bioactive oxazines and thiazines under ultrasonic irradiation

A synergistic catalysts system ZnO NPs and Malic acid was used for the highly efficient and eco-friendly synthesis of oxazines and thiazines derivatives. Aldehyde, urea and alkyne derivatives are used as reactants under ultrasonication, which not only allows clean and rapid alteration but also simplifies experimental setup. High yields, environmentally benigness, simple work-up and shorter reaction times are some remarkable advantages of this strategy. (C) 2019 Elsevier B.V. All rights reserved.

Dual Roles of beta-Oxodithioesters in the Copper-Catalyzed Synthesis of Benzo[e]pyrazolo[1,5-c][1,3]thiazine Derivatives

A facile and efficient method for the chemoselective synthesis of benzo [e]pyrazolo [1,5-c] [1,3]thiazine derivatives has been developed by tandem Ullmann Coupling reactions of beta-oxodithioesters (ODEs) with 3-(2-bromoaryl)-1H-pyrazoles in C-S bond formation manner, in which ODEs play dual roles as both a substrate and a ligand. A series of benzo[e]pyrazolo[1,5-c][1,3]thiazine derivatives were provided in good to excellent yields with CuI as the copper source in the presence of NaOH in CH3CN at 80 degrees C Under a N-2 atmosphere.

Crystal structure of the 1 : 1 adduct of 2,3-diphenyl-3,4,5,6-tetrahydro-2H-1,3-thiazin-4-one with triphenyltin chloride

The title adduct, chlorido(2,3-diphenyl-3,4,5,6-tetrahydro-2H-1,3-thiazin-4-one-kappa O) triphenyltin, [Sn(C6H5)(3)Cl(C16H15NOS)], resulted from reaction of 2,3-diphenyl- 3,4,5,6-tetrahydro-2H-1,3-thiazin-4-one with triphenyltin chloride. The thiazine ring has an envelope conformation with the S atom forming the flap. The molecule has five phenyl rings, two of them attached to the thiazine ring at positions 2 and 3, and three in coordination with the Sn-IV atom. The three rings of the triphenyltin group are involved in intramolecular interactions of different types, C-H center dot center dot center dot O, edge-to-face (or T-type) pi-pi interactions with the 3-phenyl ring of the thiazine, T-type interactions with both phenyl rings of the thiazine etc. On the other hand, all the phenyl rings participate in intermolecular pi-pi interactions. There is one instance of a ‘parallel-displaced’-type interaction extending continuously along the a-axis direction and seven instances of T-type interactions stabilizing the crystal lattice.

A facile access and evaluation of some novel thiazole and 1,3,4-thiadiazole derivatives incorporating thiazole moiety as potent anticancer agents

Background: Many heterocyclic compounds containing thiazole or 1,3,4-thiadiazole ring in their skeletons have been reported to possess various pharmacological activities especially anticancer activities. Results: 4-Methyl-2-phenylthiazole-5-carbohydrazide (2) was used as a synthon to prepare 2-(4-methyl-2-phenylthiazole-5-carbonyl)-N-phenylhydrazinecarbothioamide (3) and 2-(2-(4-methyl-2-phenylthiazole-5-carbonyl) hydrazono)-N’-phenylpropane hydrazonoyl chlorides 5a-c. In addition, thioamide 3 was used as starting material for preparation of a new series of thiadiazole derivatives via its reaction with hydrazonoyl chlorides 5a-c in dioxane using triethylamines as catalyst. In addition, a series of thiazole derivatives was synthesized by reaction of thioamide 3 with a number of a-halo compounds, namely, 3-chloropentane-2,4-dione (8) or 2-chloro-3-oxo-N-phenyl butanamide (10) phenacyl bromide 12 ethyl chloroacetate (14) in EtOH in the presence of triethylamine. The structures assigned for all the new products were elucidated based on both elemental analyses and spectral data and the mechanisms of their formation was also discussed. Moreover, the new products was evaluated in vitro by MTT assays for their anticancer activity against cell lines of Hepatocellular carcinoma cell line (HepG-2). The best result observed for compounds 7b (IC50 = 1.61 +/- 1.92 (mu g/mL)) and 11 (IC50 = 1.98 +/- 1.22 (mu g/mL)). The structure-activity relationships have been suggested based on their anticancer results. Conclusions: A novel series of new pharmacophores containing thiazole moiety have been synthesized using a facile and convenient methods and evaluated as potent anticancer agents.

New pyrimidothiazine Derivative as Corrosion Inhibitor for Carbon Steel in Acidic Media

2,8-bis(4-chlorophenyl)-3-hydroxy-4,6-dioxo-4,6-dihydropyrimido[2,1-b][1,3]thiazine-7-carbonitrile (CHPTC) was tested as corrosion inhibitor for carbon steel in 2.0 M H3PO4 by using polarization, electrochemical impedance spectroscopy (EIS) and computational calculations. Potentiodynamic polarization curves indicated that the pyrimidothiazine derivativeas mixed-type inhibitor. Impedance measurements showed that the double-layer capacitance decreased and charge-transfer resistance increased with increase in the inhibitor concentration and hence increasing in inhibition efficiency. The effect of temperature on the corrosion behavior of carbon steel in 2.0 M H3PO4 with and without addition of CHPTC was studied in the temperature range 313-333 K. The adsorption of the inhibitor molecules was in accordance with the Langmuir adsorption isotherm. Quantum chemical approach used to calculate electronic properties of the molecule to ascertain the relation between inhibitive effect and molecular structure.

Synthesis and In Vitro Anticancer Evaluation of Symmetrically Bridged 1,3-thiazine Derivatives

A series of bis-1,3-thiazine derivatives 3a-o were synthesized from the condensation reactions of symmetric dialdehydes 1a-c possessing aliphatic ether spacer units with 3-substituted-amino-2-cyano-3-mercaptoacrylamides 2a-e. The chemical structures of the products were fully characterized by using different spectroscopic techniques, such as H-1 NMR, C-13 NMR, IR, electron impact mass spectrometry, and elemental analysis. Compounds 3a, 3f, and 3k underwent ring opening followed by recyclization and alkylation in basic medium to afford bis-pyrimidinones 4a-c and 5a-c. The anticancer potential of the new bis-1,3-thiazines was assessed in vitro against six different human cell lines, including lung A549, colon HCT116, breast MCF-7, prostate PC3, liver HepG2, and normal melanocyte HFB4. The results revealed a potent activity of compounds 3e and 3k against breast and liver cancer cell lines in comparison with the reference drug doxorubicin with no noticeable toxicity on normal cells.
