Potential new targets for antimalarial chemotherapy include parasite proteases, which are required for several cellular functions during the Plasmodium falciparum life cycle. Four new derivatives of N-alkyl and N-benzyl-1,10-phenanthroline have been synthesized. Those are (1)-N-methyl-1,10-phenanthrolinium sulfate, (1)-N-ethyl-1,10-phenanthrolinium sulfate, (1)-N-benzyl-1,10-phenanthrolinium ch...

Preservatives are chemical substances whose role is to protect medicinal products against harmful changes caused by microorganisms. They are added to sterile medicinal products, such as eye drops and multidose solutions for injections, as well as to non-sterile products, such as water oral solutions, creams, gels, suppositories and capsules with liquid content. The most commonly used preservati...

Muramic acid is found in many peptide natural products containing oligo(poly)saccharide moieties. Taking into consideration that the Fmoc methodology is routinely used for solid-phase peptide synthesis, preparation of orthogonally protected muramic acid building blocks for total solid-phase synthesis of these natural products is of particular practical importance. Herein a simple and efficient ...

In the title compound, C(20)H(22)O, the mol-ecule is a meso isomer with the two benzyl groups cis to each other. The central cyclo-hexa-none ring adopts a chair conformation. The mol-ecule lies on a noncrystallographic mirror plane and the dihedral angles of the benzyl groups with respect to the ketone moiety are 88.06 (6) and 89.07 (6)°.

Two novel succinimide-based palladium complexes, AsCat and FurCat, are highly efficient catalysts for room-temperature Stille cross-coupling of organostannanes with benzyl chlorides. The air- and moisture-stable catalysts are prepared in one step, and the coupling reactions proceed with a high selectivity for the benzyl position under mild conditions without the need for additives.

The purpose of this study was to evaluate the effects of different levels of salinity stress and sprayed of the 6-benzylaminopurine (benzyl adenine) on morphological and biochemical characteristics of winter jasmine. Therefore, an experiment was conducted in 2016-2017 growing seasons in research center of greenhouse production of Islamic Azad University, Isfahan (Khorasgan) Branch. The experime...

The title compound, 4-amino-5-benzoyl-1-benzyl-2-(4,5,6,7-tetrahydro-1H-indol-2-yl)- 1H-pyrrole-3-carbonitrile, was synthesized for the first time in a 40% yield by reaction of N-benzyl-3-imino-5,6,7,8-tetrahydro-3H-pyrrolo[1,2-a]indol-1-amine and 1-chloroacetophenone K2CO3/MeCN system (reflux, 6 h). product characterized 1H-NMR, 13C-NMR, IR spectroscopy, elemental analysis.

The title compound, C(20)H(22)Cl(2)N(3)O(4)PS, was synthesized by the reaction of N-(4-methoxy-benzyl-idene)-5-(2,4-dichloro-phenyl)-1,3,4-thia-diazol-2-amine and diethyl phosphite. In the crystal, inter-molecular C-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules.

The selective preparation of monobenzyl glyceryl ethers, which are potential commodity chemicals with special functions, was explored to find new applications for glycerol. Among the acid catalysts investigated (sulfuric acid, heteropoly acid, Nafion(R), and zeolite), Zeolite Socony Mobil-5 (ZSM-5) afforded better results. The reaction of equimolar amounts of glycerol and benzyl alcohol at 150º...
