N-Alkyl derivatives of 2-amino-2-deoxy-D-glucose

Mono- and di-N-alkylated derivatives of 1,3,4,6-tetra-O-acetyl-2-amino-2- deoxy-beta-D-glucose (alkyl = methyl, ethyl, propyl, butyl, pentyl, hexyl, benzyl) were synthesised by the reductive alkylation of per-O-acetyl-d- glucosamine. (N-ethyl, N-propyl, N-butyl, N-pentyl and N-hexyl)-1,3,4,6-tetra-O- acetyl-2-amino-2-deoxy-beta-D-glucoses were deacetylated in order to attempt an enzymatic phosphorylation. All products were characterised by means of IR, NMR and MS spectra. N-Ethyl- and N-pentyl-D-glucosamines were found to exhibit weak antifungal activity.

Solid and solution structures of ternary gold(I) complexes with triphenylphosphine and nitrogen-containing ligands

A series of gold(I) complexes [Au(PPh3)L]ClO4 (L = pyridine 1a, 2,6-dimethylpyridine 1b, 2,6-di-tert-butylpyridine 1c, quinoline 1d, acridine 1e, benzo[h]quinoline 1f, naphthyridine 2a, 1,10-phenanthroline 2b, 2,2?-biquinoline 2c, di-2-pyridyl ketone 2d, di-2-pyridylamine 3a or 2-(2-pyridyl)benzimidazole 3b) were prepared by reaction of L with [Au(PPh3)(ClO4)] which was synthesized in situ. All complexes were characterized by IR, UV/VIS and 1H NMR spectroscopy. The crystal and molecular structures of 1b, 2a and 3b were investigated by single-crystal X-ray diffraction techniques. The gold(I) is co-ordinated to one nitrogen atom and one phosphine atom. Detailed 1H NMR studies suggested that linear two-co-ordinated structures persist in solution and further that all the complexes [Au(PPh3)L]ClO4, (2a-2d), are fluxional species in which the co-ordination site of gold(I) rapidly exchanges between two nitrogen atoms of the ligand.

Construction of Zn(II)-ferrocenyl carboxylate coordination complexes via changing adjuvant ligands

Five Zn(II)-ferrocenyl carboxylate complexes, {[Zn(OOCClH3C 6Fc)(2OOCClH3C6Fc)(dpa)] (H2O)} (1), [Zn(2-OOCClH3C6Fc)2(2,20-dip)] (H2O)0.25} (2), {[Zn(-OOCClH3C6Fc)2(bix)]2 (THF)} (3), [Zn(-OOCClH 3C6Fc)2 (Hfcz)]n (4) and {[Zn(-OOCClH3C 6Fc)2 (H2L1)] (DMF)2}n (5) [dpa2,20-dipyridylamine, 2,20-dip2,20-bipyridine, bix1,4-bis (imidazol-1-ylmethyl)benzene, Hfcz-(2,4-difluorophenyl)-(1H-1,2,4-triazol-l-ylmethyl)-1H-1,2, 4-triazole-l-ethanol, H2L1N,N0-bis(pyridin-4-yl)pyridine-2,6-dicarboxamide, Fc ferrocene, FcC6H3ClCOONasodium 2-chloro-4-ferrocenylbenzoic], have been synthesized and characterized. Single-crystal X-ray analysis reveals that 1 and 2 are mononuclear structures, 3 is a dimer, and 4 and 5 are 1-D structures. The five complexes exhibit some differences in their conformations, which can be attributed to the influence of adjuvant ligands. Notably, various pi-interactions as well as CH/piinteractions are discovered in 1-5, and they have significant contributions to self-assembly. The electrochemical properties of 1-5 indicate that half-wave potentials shift to positive potential compared with that of 2-chloro-4-ferrocenylbenzoic acid.

The Mn(II)-2,2?-dipyridylamine-pseudohalide system: Synthesis, crystal structure and luminescence behaviour of [Mn(dpa)2(X) 2]·H2O and [Mn(dpa)2(X)(OH 2)]ClO4 (dpa = 2,2?-dipyridylamine; X = N 3-, NCO-)

Four complexes of the type [Mn(dpa)2(X)2] ·H2O (dpa = 2,2?-dipyridylamine; X = N3 -,1; X = NCO-, 2) and [Mn(dpa)2(X)(OH 2)]ClO4 (X = N3-, 3; X = NCO -, 4) have been synthesized using single-pot reactions of manganese(II) salt, dpa and X in 1:2:2 and 1:2:1 molar ratios, respectively. The compounds have been characterized by microanalytical, physicochemical, spectroscopic and magnetic results. Room temperature magnetic moments (mueff) are in the range 5.88-5.97 BM and are typical of high-spin manganese(II) complexes (t2g5 idealized, S = 5/2). The complexes display a Mn(III)-Mn(II) couple at ?0.6 V versus SCE in DMF solutions. X-ray structure determinations show that in 1-4 the manganese(II) centres are in a distorted octahedral environment. Compounds 1 and 2 contain the MnN6 chromophore, completed by two bidentate dpa units and two terminal azido groups in 1 or N-coordinated cyanato ligands in 2, along with a water of crystallization. In 3 and 4, one water molecule acts as a coordinating ligand replacing one of the terminal pseudohalides in 1 and 2, respectively, resulting in a MnN5O chromophore. The amine H, terminal azido N or cyanato O, O and H’s of the water molecule are engaged in extensive hydrogen bonding of the type N-H?N, O-H?N and N-H?O in 1 and 2. Additionally O-H?O bonding is observed in 3 and 4. Supramolecular 2D sheet structures are obtained arising from such weak intermolecular forces. All the complexes display high-energy intraligand 1(pi-pi*) fluroscence and intraligand 3(pi-pi*) phosphorescence in glassy solutions (DMF at 77 K).

Low-budget 3D-printed equipment for continuous flow reactions

This article describes the development and manufacturing of lab equipment, which is needed for the use in flow chemistry. We developed a rack of four syringe pumps controlled by one Arduino computer, which can be manufactured with a commonly available 3D printer and readily available parts. Also, we printed various flow reactor cells, which are fully customizable for each individual reaction. With this equipment we performed some multistep glycosylation reactions, where multiple 3D-printed flow reactors were used in series.

Dichloro-cyanoacetimidates as glycosyl donors

Transformation of 1-O-unprotected glucose and galactose derivatives (1a-d) into O-glycosyl dichloro-cyanoacetimidates (2a-d) was performed with dichloro-cyanoacetonitrile in the presence of DBU as base. Reaction with different acceptors (3a-d) under TMSOTf catalysis afforded glycosides 4 in high yields. Competition experiments with O-glucopyranosyl trichloroacetimidate 10a, bearing a 4-tert-butylbenzyl group at 6-O, and O-glucopyranosyl dichloro-cyanoacetimidate 10b, bearing a 4-methylbenzyl group at 6-O, displayed similar reactivities for these two types of glycosyl donors.

Synthesis, structural, thermal characterization and interaction with calf-thymus DNA and albumins of cationic Ni(II) complexes with 2,2?-dipyridylamine and salicylaldehydes

Five cationic mixed-ligand Ni(II) complexes with 2,2?-dipyridylamine (dpamH) and substituted salicylaldehydes (X-saloH), having the general formula [Ni(dpamH)2(X-salo)](NO3), were prepared and characterized by physicochemical and spectroscopic techniques (FT-IR and UV?vis) and their interaction with calf-thymus (CT) DNA and serum albumins was investigated. The complexes are formulated as [Ni(dpamH)2(3-OCH3-salo)](NO3)·CH3OH, 2, [Ni(dpamH)2(5-CH3-salo)](NO3)·CH3OH, 3, [Ni(dpamH)2(5-NO2-salo)](NO3)·CH3OH, 4, [Ni(dpamH)2(5-Cl-salo)](NO3), 5 and [Ni(dpamH)2(5-Br-salo)](NO3), 6. Moreover, in the absence of dpamH, one neutral nickel-salicylaldehydato complex was also prepared and characterized as [Ni(5-NO2-salo)2(CH3OH)2], 1. The structures of complexes 2 and 4 were verified by X-ray crystallography. The thermal stability of the complexes was examined by the simultaneous thermal analysis technique (TG/DTG-DTA). Spectroscopic (UV?vis), electrochemical (cyclic voltammetry) and physicochemical (viscosity measurements) techniques were employed in order to study the binding mode and binding strength of the complexes to CT DNA, while ethidium bromide (EB) displacement studies (performed by fluorescence emission spectroscopy) revealed the ability of the complexes to displace the DNA-bound EB. Intercalation is the most possible mode of interaction of the complexes with CT DNA. The interaction of the complexes with albumins was studied by fluorescence emission spectroscopy and the determined binding constants present relative high values.
