The condensation of 4H-1,2,4-triazol-3-amine with ortho esters derived from acetic, propionic, and benzoic acids gave the corresponding N-(4H-1,2,4-triazol-3-yl) carboximidates which were treated with cyanamide, carbon disulfide, and sodium thiocyanate to afford 7-substituted [1,2,4]triazolo[4,3-a][1,3,5]triazin-5-amines, [1,2,4]triazolo[4,3-c][1,3,5]thiadiazine-5-thiones, and [1,2,4]triazolo[4,3-c][1,3,5]thiadiazin-5-imines, respectively. The structures of the synthesized compounds were confirmed by IR, H-1 and C-13 NMR, and mass spectra and elemental analyses.

The reactivity of iodine(III) reagents towards nucleophiles is often associated with umpolung and cationic mechanisms. Herein, we report a general process converting a range of ketone derivatives into alpha-cyclopropanated ketones by oxidative umpolung. Mechanistic investigation and careful characterization of side products revealed that the reaction follows an unexpected pathway and suggests the intermediacy of non-classical carbocations.

In this work, we describe the development of the rearrangement for 7-aryl-substituted oxazolo[S,4-b]pyridines treated with aluminum chloride into synthetically hard-to-reach benzo[c][1,7]naphthyridinones. The discovered rearrangement is applied to a variety of electron-rich (hetero)arene substrates. It offers the advantages of mild conditions (90 degrees C temperature), fast reaction rates (<4 h), compatibility with air moisture, and the use of inexpensive commercial reagents. The proposed reaction mechanism and key elementary reaction acts were studied in detail using quantum chemical calculations. The photophysical properties of the synthesized compounds were studied by steady-state UV-vis spectroscopy. Name: 1,1,1-Triethoxyethane.

In spite of the fact that a variety of reactions have been exploited for creation of innumerable porous organic polymers (POPs), aldol condensation reactions between aldehydes and ketones leading to enones remain unutilized quite inexplicably. We surmised that the enone functionality can be exploited for stabilization of Pd akin to the manner of Pd(0) in Pd-2(dba)(3) by developing POPs based on aldol condensation reactions of polycarbonyl compounds with dialdehydes, and that such materials can be employed for catalytic transformations. By subjecting rationally designed tri-/tetraacetyl-functionalized aryl amines to aldol condensations with terephthalaldehyde, three different POPs, i.e., TPAPOPs 1-3, that feature enone functionalities have been synthesized and shown to exhibit palpable gas sorption properties. Remarkably, inverse uptake for sorption of H-2 over N-2 was observed for all POPs. As surmised, the representative POP, i.e., TPAPOP-1, was found to stabilize in situ-generated Pd(0) nanoparticles to enable application of the resultant material, i.e., Pd@TPAPOP-1, as a recyclable heterogeneous catalyst for a number of organic transformations. It is shown that coupling reactions such as Suzuki and Heck, and reductions such as nitro-to-amine and hydrogenation of olefins can be accomplished in a facile manner by employing Pd@TPAPOP-1 as a heterogeneous recyclable catalyst; the aforementioned transformations have been demonstrated on a broad set of substrates for each type.

We herein report highly chemoselective transfer hydrogenation of alpha,beta-unsaturated carbonyl compounds to saturated carbonyls with formic acid as a hydrogen donor over a stable and recyclable heterogeneous Pd nano particles (NPs) on N,O-dual doped hierarchical porous biomass-derived carbon. The synergistic effect between Pd NPs and incorporated heteroatoms on carbon plays a critical role on promoting the reaction efficiency. A series of alpha,beta-aromatic and aliphatic unsaturated carbonyl compounds was selectively reduced to their corresponding saturated carbonyls in up to 97% isolated yields with good tolerance of various functional groups. In addition, the catalyst can be successively reused for at least 6 times without significant loss in reaction efficiency.

The synthesis of a series of novel 7-aminooxazolo[5,4-d]pyrimidines5, transformations during their synthesis and their physicochemical characteristics have been described. Complete detailed spectral analysis of the intermediates2-4, theN ‘-cyanooxazolylacetamidine by-products7and final compounds5has been carried out using MS, IR, 1D and 2D NMR spectroscopy. Theoretical research was carried out to explain the privileged formation of 7-aminooxazolo[5,4-d]pyrimidines in relation to the possibility of their isomer formation and the related thermodynamic aspects. Additionally, the single-crystal X-ray diffraction analysis for5hwas reported. Ten 7-aminooxazolo[5,4-d]pyrimidines5(SCM1-10) were biologically tested in vitro to preliminarily evaluate their immunological, antiviral and anticancer activity. CompoundsSCM5andSCM9showed the best immunoregulatory profile. The compounds displayed low-toxicity and strongly inhibited phytohemagglutinin A-induced proliferation of human peripheral blood lymphocytes and lipopolysaccharide-induced proliferation of mouse splenocytes. CompoundSCM9caused also a moderate suppression of tumor necrosis factor alpha (TNF-alpha) production in a human whole blood culture. Of note, the compounds also inhibited the growth of selected tumor cell lines and inhibited replication of human herpes virus type-1 (HHV-1) virus in A-549 cell line. Molecular investigations showed that the compounds exerted differential changes in expression of signaling proteins in Jurkat and WEHI-231 cell lines. The activity ofSCM5is likely associated with elicitation of cell signaling pathways leading to cell apoptosis. The compounds may be of interest in terms of therapeutic utility as inhibitors of autoimmune disorders, virus replication and antitumor agents.

Aim: There is a continuous and urgent need for new anticancer agents with novel structures and target selectivity. Methods & results: The anticancer activity of the prepared compounds was assessed against human lung (A549) and stomach (AGS) cancer cell lines and evaluated in the noncancer human lung fibroblast (MRC-5) cell line. 2-Pyrazolines were devoid of toxicity in all cell lines used, chalcones bearing a beta-(benz)imidazole moiety being toxic toward AGS cell line. Mechanistic studies showed that these compounds trigger loss of cell viability and mitochondrial membrane potential, while eliciting morphological traits compatible with regulated cell death, which was ultimately shown to derive from caspase activation, specifically caspase-3. Conclusion: Chalcones 1-3 have been identified as new and promising anticancer agents toward the AGS cell line.

A new and simple method for the deoxygenation of ketones to alkanes is presented. Most substrates are reduced under mild conditions by triethylsilane in the presence of catalytic amounts of [Rh(mu-Cl)(CO)(2)](2). This system selectively provides the methylene hydrocarbons in good to excellent yields starting from acetophenones and diaryl ketones. A rapid examination of the reaction pathway suggests that the ketone is first converted into an alcohol, which then undergoes hydrogenolysis to give the alkane.
