Mechanism of acid hydrolysis of N-acetyl-D-glucosamine

The hydrolysis kinetics of the chitin monomer, N-acetyl-D-glucosamine, in HCl, HClO4, and H3PO4 was studied in relation to the acid concentration. The rate constants of N-acetyl-D-glucosamine deacetylation and D(+)-glucosamine formation in HClO4 and H 3PO4 were determined for the first time. The rate of the acetamide bond hydrolysis in N-acetyl-D-glucosamine depends on the concentrations of hydrogen ions and water. The nucleophilicity of the acid residues does not affect the rate of N-acetyl-D-glucosamine hydrolysis.

Decarbonylation of Unprotected Aldose Sugars by Chlorotris(triphenylphosphine)rhodium(I). A New Descent of Series Approach to Alditols, Deoxyalditols, and Glycosylalditols

Unprotected Cn aldose sugars are cleanly decarbonylated by 1 equiv of chlorotris(triphenylphosphine)rhodium(I) in 1-24 h at 130 deg C in N-methyl-2-pyrrolidinone solution to give the corresponding Cn-1 alditol in about 75-95percent yields.This technique represents a useful variation on traditional carbohydrate “descent of series” reactions.The procedure is quite general and also works on a number of aldose derivatives, such as deoxy sugars, N-acetylated amino sugars, and disaccharides, providing convenient small-scale syntheses of deoxyalditols, (acetylamino)deoxyalditols, and glycosylalditols, respectively.The reactions proceed with complete retention of stereochemistry, the only side products observed being a few percent of the Cn lactones and the Cn-2 alditol.Attempts to make the reactions catalytic have not yet been very successful.

A one-pot synthesis of novel sugar derived 5,6-dihydro-quinazolino[4,3-b]quinazolin-8-ones: an entry towards highly functionalized sugar-heterocyclic hybrids

An efficient and practical one-pot method for the synthesis of novel diversified sugar derived dihydro-quinazolino[4,3-b]quinazolin-8-ones has been reported. Various protected sugar hemiacetals were used to synthesize the hybrid tetracyclic ring system. The one-step reductive transformation of 2-(2-nitrophenyl)-3H-quinazolin-4-one with different sugar hemiacetals furnished the desired tetracyclic product in good yields and with high purity.

Electron Delocalization of Mixed-Valence Diiron Sites Mediated by Group 10 Metal Ions in Heterotrimetallic Fe-M-Fe (M=Ni, Pd, and Pt) Chain Complexes

The heterotrimetallic complexes [FeMFe(dpa)4Cl2] (M=Ni (1), Pd (2), and Pt (3); dpa?=dipyridylamido) featuring two high-spin iron centers linked by Group 10 metals were synthesized and their physical properties were investigated. Oxidation of 1?3 with suitable oxidants in CH2Cl2 solution yielded the mixed-valent species [1]+/2+?[3]+/2+. The solution properties of [1]0/+/2+?[3]0/+/2+ were characterized by 1H NMR and UV/Vis/NIR spectroscopy as well as spectroelectrochemisty. The mixed-valent states of [1]+?[3]+ obtained by electrochemical or chemical oxidation are classified as class II valence delocalization. The solid-state structures of 1?3, [1]+, [3]+, and [1]2+ were determined by single-crystal X-ray diffraction analysis, exhibiting a linear metal framework with an approximate D4 symmetry. The spin states and magnetic properties were studied by using SQUID magnetometry, EPR and Moessbauer spectroscopy, and DFT calculations. Antiferromagnetic interactions between terminal high-spin iron centers are present within [1]0/+/2+?[3]0/+/2+ and the |J| values increase with the central metal ion changing from Ni to Pt. The DFT calculations reproduce the antiferromagnetic coupling and ascribe it to a sigma-type exchange pathway. The substitution of the central metal not only influences the spin?spin interactions but also the degree of electronic delocalization between the terminal iron sites along the Fe-M-Fe chains.

Tetrahydroquinoline derivatives as opioid receptor antagonists

Opioid receptors play an important role in both behavioral and homeostatic functions. We herein report tetrahydroquinoline derivatives as opioid receptor antagonists. SAR studies led to the identification of the potent antagonist 2v, endowed with 1.58 nM (Ki) functional activity against the mu opioid receptor. DMPK data suggest that novel tetrahydroquinoline analogs may be advantageous in peripheral applications.

Influence of hydrogen bonding interactions on the conformation of ribbon-like Zn(II) complexes bridged by molybdates

The complexes [Zn(dpa)MoO4] (1) and [Zn(dpa)MoO 4]¡¤0.5H2O (2¡¤0.5H2O) (dpa = 2,2?-dipyridylamine) were synthesized hydrothermally. Single crystal structure analyses indicate that 1 and 2 are conformational isomers. They both consist of binuclear units of edge-sharing {ZnN2O3} trigonal bipyramids bridged by pairs of bidentate briding {MoO4} 2- anions into a one-dimensional ribbon, but their orientations of the terminal O atoms of the {MoO4}2- anions are different. In 1 and 2, the ribbon-like chains are connected into a 2D network via hydrogen bonding interactions between the central N-H portions of the dpa molecules and the terminal O atoms of {MoO4} tetrahedra. For 2, in addition, the hydrogen bonding interactions between the crystal water molecules and the terminal O atoms of {MoO4} tetrahedra join the 2D layers into a 3D architecture. They play an important role not only in constructing the 3D architecture, but also in the conformational stability.
