Sulfonamides are very important scaffold in design of different compounds with potential biological activity. They are the basis of several groups of drugs and could be called sulfa drugs. Starting from this fact, we wanted to synthesize some new types of sulfonamides, prepared from derivatives of natural product vanillin. In light of this, we synthesized dehydrozingerone, 4-(4-hydroxy-3-methoxyphenyl)-3-buten-2-one, and its alkyl derivatives. These compounds served as good substrates in the synthesis of new sulfonamide compounds. The structures of the new compounds were determined by IR and NMR methods. Cytotoxicity screening of fourteen new organic compounds against SW480, Hela and MRC-5 was measured by colorimetric MTT assay after 48h of treatment. Cytotoxicity ratio (CR) was calculated as % of cytotoxicity of each compound on normal cells and % of cytotoxicity of the same compounds on tumor cell line. CR is pointed to some new compounds as promising candidates for further experiments.

A series of 25 compounds were synthesized based on structure modification of the model methyl 3-(4-chlorophenyl)-3-hydroxy-2,2-dimethylpropanoateas potent HDACIs. Saponification and hydrazinolysis of the model ester afforded the corresponding acid and hydrazide, respectively.The model ester was transformed into corresponding trichloroacetimidate or acetate by the reaction with trichloroacetonitrile and acetic anhydride, respectively. N -alkyl-3-(4-chlorophenyl)-3-hydroxy-2,2-dimethylpropan-amides and methyl 2-[(3-(4-chlorophenyl)-3-hydroxy-2,2-dimethylpropanoyl)amino] alkanoates were obtained by the reaction ofcorresponding acid or hydrazide with amines andamino acid esters via DCC and azidecoupling methods. Methyl 3-aryl-3-(4-chlorophenyl)-2,2-dimethylpropanoates were obtainedin good yields and short reaction timefrom the corresponding trichloroacetimidate or acetate by the reaction with C -active nucleophiles in the presence of TMSOTf(0.1eq %) via C-C bond formation. acetate

Since Pb(II) is one of the toxic water contamination agents, finding an efficient way to remove it from wastewater has become a serious issue in the world. Herein, a metal-organic framework, formulated as (TMU-23), with amide-decorated pores was prepared to investigate its potential in Pb(II) removal performance. At first, various determining factors including pH and adsorbent dosage were optimized. Then, the MOF adsorption capacity was measured about 434.7 mg. g. Moreover, reusability feature and effect of competitive cations were checked. Adsorptiondesorption tests showed that during three cycles, the MOF could act with favorable efficiency. Modeling calculations illustrate that pseudo-second-order and Langmuir models provide the best description for adsorption mode. Based on these models, monolayer adsorption behavior was responsible for adsorption process through chemical interaction between the analyte and the walls of MOF. Also, the possible adsorption mechanism was examined by exploiting of FTIR spectroscopy, EDS and SEM images. The significant affinity between amide groups of pillars and Pb(II) could cause good removal performance.

A new magnetic core/shell nanocatalyst functionalized with 1,3,5-tris(2-hydroxyethyl)isocyanurate and boric acid (Fe3O4/SiO2/CPTS/THEIC/(CH2)3B(OH)2) was designed and properly characterized by the Fourier transform infrared (FTIR) spectroscopy, nitrogen adsorption–desorption technique (BET), thermal gravimetric analysis (TGA) and X-ray diffraction (XRD), vibrating sample magnetometer (VSM), field emission scanning electron microscopy (FESEM) and energy-dispersive X-ray (EDX) spectroscopy. The catalytic activity of Fe3O4/SiO2/CPTS/THEIC/(CH2)3B(OH)2, as an efficient magnetically recoverable catalyst, was investigated for the synthesis of polyhydroquinolines (PHQs) as well as polyhydroacridines (PHAs) via one-pot multicomponent reactions of ethyl acetoacetate and / or dimedone, different aldehydes and ammonium acetate in EtOH under reflux conditions. High to quantitative yields of the desired PHQs or PHAs products, wide scope of the substrates, eliminating of any toxic heavy metals or corrosive reagents for modification of the catalyst, simple work-up procedure, short reaction times and low loading of the catalyst are remarkable advantages of this green protocol. An additional advantage of this magnetic nanoparticles catalyst is its ability to be separated and recycled easily from the reaction mixture with minimal efforts in six subsequent runs without significant loss of its catalytic activity.

Treatment of the latter with palladium acetate gives tetranuclear structures with two ligand moieties linked by acetate-bridging ligands. The addition of ddpm (4 equivalents) provides doubly metallated structures where the phosphine acts as a bidentate chelating ligand.

Since the appearance of the term palladacycle, as coined by Trofimenko[1], one of the most salient groups is the one comprising thiosemicarbazones. Herein, the synthesis and characterization of several palladium cyclometallated compounds with thiosemicarbazone ligands is discussed. The ligands were synthesized by treatment of a ketone with four different thiosemicarbazides in acidified aqueous solution. Then, they were conveniently treated with a palladium salt to yield the corresponding palladacycle. All show a tetranuclear structure with [C, N, S] coordination of the ligands to the metal centers.

Abstract: We reported a novel sophisticated synthetic method for preparation of monosubstituted piperazine derivatives, which can now be easily prepared in a one-pot-one-step way from a free piperazine with no need of introduction of a protecting group bringing further disadvantages in terms of time, costs and reduced yields. Reactions proceeding either at room or higher temperatures in common solvents employ with advantage heterogeneous catalysis by metal ions supported on commercial polymeric resins.

: We report characterization data of novel graphene-like materials prepared by new cheap and environmentally friendly synthetic methods. FT-IR, Raman and X-ray photoelectron spectroscopy, scanning electron microscopy and thermal and elemental analysis methods were used to describe features of novel graphene-like materials and obtained data were compared with the data of commercial standards. It was found that employment of gentle oxidizing agents supported by ultrasound action instead of harsh oxidizers and strongly acidic solutions provides a-few-layer graphene oxides with low-defect layers in high yields. Although keeping the same level of oxidation like commercial standards new products are more stable due to a lower damage of carbon layers. Obtained products can then be further modified to reduced graphene oxides or amine-modified derivatives. All of the characterization data are presented and discussed in the article.
