Synthesis of magnetic hollow mesoporous N-doped silica rods as a basic catalyst for the preparation of some spirooxindole-1,4-dihydropyridine derivatives

In this study, magnetic hollow mesoporous N-doped silica rods were successfully prepared via the in-situ calcination of different amounts of diethanolamine in the presence of silica precursor. Doping of the nitrogen atoms in to silica rod structures was performed through a new method and the structure of obtained composite confirmed by X-ray photo electron spectroscopy (XPS), X-ray diffraction (XRD) analysis, elemental analysis, TEM, FESEM and elemental mapping methods. Comparison of the synthesized N-doped catalyst with the same sample without nitrogen atoms (mesoporous silica) showed the high basic characteristic. Furthermore, the efficiency of the prepared basic catalyst was investigated for the synthesis of some spirooxindole-1,4-dihydropyridine derivatives under green conditions. High efficient heterogeneous catalyst, short reaction times (compare with other reported methods) and green conditions are some advantageous of presented method.

One-step synthesis of O-benzyl hydroxamates from unactivated aliphatic and aromatic esters

We have developed a simple and high yielding one-step method for the synthesis of hydroxamate derivatives directly from a broad range of unactivated esters and the anion of O-benzyl-hydroxylamine generated in situ. The reaction takes place in minutes at -78 C. Very importantly, the method was successfully employed with enolizable esters, including chiral alpha-amino acid esters and peptides, with no trace of racemization/epimerization at the alpha carbon detected.

Effect of process parameters on supercritical liquefaction of Xanthium strumarium for bio-oil production

Supercritical liquefaction process is used for producing energy from biomass. The common reaction conditions for supercritical liquefaction process are the 240-380 C temperature range and 5-20 MPa pressure values range. Xanthium strumarium liquefaction experiments were performed in a cylindrical reactor (75 mL) in organic solvents (acetone, ethanol, methanol) under supercritical conditions with (zinc oxide, calcium hydroxide) and without catalyst at the temperatures of 250, 275 and 300 C. The produced liquids at 300 C in liquefaction were analyzed and characterized by Elemental, GC-MS and FT-IR. 36, 37 and 50 different types of compounds were identified by GC-MS obtained in acetone, ethanol and methanol respectively. The liquid product efficiency has been obtained at 300 C in acetone with zinc oxide catalyst (74.80%). The highest HHV value has been calculated as 32.16 MJ/kg with calcium hydroxide catalyst in acetone.

Predictive QSAR modeling for the antioxidant activity of natural compounds derivatives based on Monte Carlo method

Abstract: In this research, QSAR modeling was carried out through SMILES of compounds and on the basis of the Monte Carlo method to predict the antioxidant activity of 79 derivatives of pulvinic acid, 23 of coumarine, as well as nine structurally non-related compounds against three radiation sources of Fenton, gamma, and UV. QSAR model was designed through CORAL software, as well as a newer optimizing method well known as the index of ideality correlation. The full set of antioxidant compounds were randomly distributed into four sets, including training, invisible training, validation, and calibration; this division was repeated three times randomly. The optimal descriptors were picked up from a hybrid model by the combination of the hydrogen-suppressed graph and SMILES descriptors based on the objective function. These models? predictability was assessed on the sets of validation. The results of three randomized sets showed that simple, robust, reliable, and predictive models were achieved for training, invisible training, validation, and calibration sets of all three models. The central decrease/increase descriptors were identified. This simple QSAR can be useful to predict antioxidant activity of numerous antioxidants.
