1,3-Dimethyl-2,6-diphenylpiperidin-4-one N(4?)-cyclohexylsemicarbazone (DDPCS) has been synthesized and characterized by IR, 1H NMR and 13C NMR spectral analysis. IR and NMR spectra of compound DDPCS have been simulated by computational method using DFT-B3LYP with the 6?31 G basis set. Single crystal X-ray diffraction analysis has been performed and it evidences the configuration about C=N double bond is ?E ?and the chair conformation of the heterocyclic ring. The N?H????O intermolecular hydrogen bonding in the crystal structure forms an eight membered pseudo ring with the R2 2 (8), Etter’s graph set. The computational, spectral and X-ray structural results exemplifies the chair conformation of the heterocyclic ring with the equatorial orientation of bulky groups. The calculated vibrational frequencies of the normal modes accorded well with the experimental values. Hirshfeld surface analysis was also carried out and discussed in detail. The synthesized compound was screened for its in vitro antimicrobial activity.

Alkylidenetitanium reagents enable the reagent-controlled high throughput asymmetric synthesis of 2-substituted piperidines and rapid access to multiple cyclic imines using solid phase synthesis (SPS). The Schrock carbenes, generated by reduction of thioacetals, convert resin-bound esters into enol ethers. Treatment with acid releases amino ketones that are cyclized with TMSCl to give iminium salts. Reduction introduces a chiral centre at C-2, whose absolute stereochemistry is determined by a phenethylamine (PEA) chiral auxiliary. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.

Electric Literature of 50541-93-0, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 50541-93-0, Name is 4-Amino-1-benzylpiperidine, molecular formula is C12H18N2. In a Article，once mentioned of 50541-93-0

Starting from the molecular simplification of (R) 4-(3,4-dibenzylpiperazine-1-carbonyl)benzenesulfonamide 9a, a compound endowed with selectivity for human Carbonic Anhydrase (hCA) IV, a series of piperazines and 4-aminopiperidines carrying a 4-sulfamoylbenzamide moiety as Zn-binding group have been designed and tested on human isoforms hCA I, II, IV and IX, using a stopped flow CO2 hydrase assay. The aim of the work was to derive structure-activity relationships useful for designing isoform selective compounds. These structural modifications changed the selectivity profile of the analogues from hCA IV to hCA I and II, and improved potency. Several of the new compounds showed subnanomolar activity on hCA II. X-ray crystallography of ligand-hCAII complexes was used to compare the binding modes of the new piperazines and the previously synthesized 2-benzyl-piperazine analogues, explaining the inhibition profiles.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Electric Literature of 50541-93-0, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 50541-93-0, in my other articles.

The increase in the volume of agricultural and agroindustrial waste, associated with improper disposal, is a growing worldwide problem. The recovery of those residues is of crucial importance, since it reduces environmental impacts, protects public health, and allows the addition of value to the materials. One of the ways of exploiting adsorbents is related to the capacity of some wastes to be used as alternative adsorbents in the efficient removal of microcontaminants in aqueous systems. This work assessed the use of agricultural and agroindustrial residues: maize straw, wheat straw, soybean straw and soybean hulls for the production of alternative adsorbents to remove iron (Fe) and manganese (Mn) in water. For each residue investigated, two different polymers were obtained for use as adsorbents, a natural polymer (cellulose/lignin) and an EDTA-modified polymer (ethylenediaminetetraacetic acid). The adsorbents were characterized through FTIR (Fourier transform infrared spectroscopy) and nitrogen content. To evaluate the efficiency of the adsorbents, kinetic tests in batch mode and determination of Lagergren pseudo-first and pseudo-second order kinetic constants were performed. The results found that the modified polymer obtained from soybean hulls (SHE) showed increased Fe (96%) and Mn (88%) removal rate, in which the pseudo-second order kinetic model presented closer results between the experimental adsorption rates and the calculated ones for the two microcontaminants under study. In general, the modified soybean hulls proved to be a promising alternative adsorbent for the removal of iron and manganese in water treatment.

A convergent synthesis to ZD3638 was proposed starting with alternative raw materials. A cost-benefit analysis for the new route was performed which demonstrated that significant savings in raw materials costs could be made over the previous linear sequence. The convergent route was then proved in principle by experimental work. LiTMP was shown to be a superior base to LDA in the modified lithiation reaction.

Obovatol, a novel lignan isolated from the leaf and stem bark of Magnolia obovata Thunb exhibits many important biological activities. To discover natural-product-based potential fungicides with novel structural skeletons, a series of Mannich base derivatives were prepared by the C-4-aminomethylated modification of obovatol and all synthesized compounds were evaluated for antifungal activities in vitro against several phytopathogenic fungi using the spore germination method and the mycelium growth rate method. Furthermore, their structures were also characterized by 1H NMR, 13C NMR, and HR-MS, and compound 2k was further analyzed by single-crystal X-ray diffraction. Among all of the derivatives, compounds 2b (IC50 = 28.68 mug/mL) and 2g (IC50 = 16.90 mug/mL) demonstrated greater inhibition of Botrytis cinerea spore germination than two positive controls, hymexazol and difenoconazole. Compounds 2c, 2f, and 2g displayed potent mycelial growth inhibition of B. cinerea with an average inhibition rate (AIR) of >90% at a concentration of 100 mug/mL. Additionally, the structure-activity relationships (SARs) suggested that the introduction of a diethylamino, pyrrolyl, 1-methyl-piperazinyl or 1-ethyl-piperazinyl groups on the C-4 position of obovatol may be more likely to yield potential antifungal compounds than the introduction of 4-phenyl-piperazinyl or 4-phenyl-piperidinyl groups.
