Syntheses of the 3- and 4-thio analogues of 4-nitrophenyl 2-acetamido-2-deoxy-beta-d-gluco- and galactopyranoside

The syntheses of 4-nitrophenyl beta-glycosides of the 3-thio and 4-thio analogues of the two principal 2-acetamido-2-deoxy-hexoses found in living systems, GlcNAc and GalNAc, are described. While synthesis of the 4-thio analogues could be achieved via nucleophilic displacements of sulfonate derivatives with thioacetate, problems with neighbouring group acetamido participation necessitated the use of sulfamidate intermediates for the 3-thio analogues. These 3- and 4-thio analogues are employed in the chemo-enzymatic synthesis of thio-oligosaccharide analogues of structures present in glycosaminoglycans, glycoproteins and glycolipids.

Hydridodimethylplatinum(IV) complexes with bis(pyridine) ligands: Effect of chelate ring size on reactivity

The effect of changing the bite angle of the dipyridyl ligand LL on the reactivity of the dimethylplatinum-(II) complexes [PtMe2(LL)] has been studied, by comparing complexes with the ligands LL = di-2-pyridylamine (DPA) or di-2-pyridyl ketone (DPK), which form a six-membered chelate ring, to compounds with 2,2?-bipyridyl derivatives, which form a five-membered chelate ring. The complex [PtMe2(DPA)] undergoes easy oxidative addition of methyl iodide to give the corresponding platinum(IV) complex [PtIMe3(DPA)]. Both [PtMe2(DPA)] and [PtMe 2(DPK)] are protonated by acids HX at low temperature to give the hydridodimethylplatinum(IV) complexes [PtHXMe2(NN)] and [PtH(S)Me2(NN)]X (S = solvent), which can exist in two isomeric forms with H trans to X or N. The structure of the complex [PtHClMe2(DPK)] was determined crystallographically. In a solution containing excess CD 3OD, extensive hydrogen/deuterium exchange occurs into the methylplatinum groups and methane product at low temperature, indicating very easy reversibility of the exchange between hydridomethylplatinum(IV) and (methane)platinum(II) complexes. The hydridomethylplatinum(IV) complexes reductively eliminate methane at room temperature in solution but have significantly higher thermal stability and undergo more extensive H-D exchange than when NN = 2,2?-bipyridyl. The reaction of [PtMe2(DPA)] with excess HCl gave [PtCl2(DPA)], and the reaction of [PtMe 2(DPK)] with excess CF3SO3H gave the aqua complex [Pt(OH2)2(DPK)](CF3SO3) 2 or the binuclear hydroxo complex [Pt2(mu-OH) 2(DPK)2](CF3SO3)2, depending on the experimental conditions.

(E)-Alkenes as replacements of amide bonds: Development of novel and potent acyclic CGRP receptor antagonists

A new class of CGRP receptor antagonists was identified by replacing the central amide of a previously identified anilide lead structure with ethylene, ethane, or ethyne linkers. (E)-Alkenes as well as alkynes were found to preserve the proper bioactive conformation of the amides, necessary for efficient receptor binding. Further exploration resulted in several potent compounds against CGRP-R with low susceptibility to P-gp mediated efflux.

Study of new mononuclear platinum group metal complexes containing eta5 and eta6 – Carbocyclic ligands and nitrogen based derivatives and formation of helices due to NH?Cl interactions

A quite general approach for the preparation of eta5- and eta6-cyclichydrocarbon platinum group metal complexes is reported. The dinuclear arene ruthenium complexes [(eta6-arene)Ru(mu-Cl)Cl] 2 (arene = C6H6, C10H14 and C6Me6) and eta5- pentamethylcyclopentadienyl rhodium and iridium complexes [(eta5- C5Me5)M(mu-Cl)Cl]2 (M = Rh and Ir) reacts with two equivalents of the ligands 2-chloro-3-(pyrazolyl)quinoxaline (L 1) and di-(2-pyridyl)amine (L2) in presence of NH 4PF6 to afford the corresponding mononuclear complexes of the type [(eta6-arene)Ru(L1)Cl]PF6 {arene = C6H6 (1), C10H14 (2) and C 6Me6 (3)}, [(eta6-arene)Ru(L 2)Cl]PF6 {arene = C6H6 (4), C 10H14 (5) and C6Me6 (6)}, and [(eta5-C5Me5)M(L1)Cl]PF 6 {M = Rh (7), Ir (8)} and [(eta5-C5Me 5)M(L2)Cl]PF6 {M = Rh (9), Ir (10)}. However the mononuclear eta5-cyclopentadienyl analogues such as [(eta5-C5H5)Ru(PPh3) 2Cl], [(eta5-C5H5)Os(PPh 3)2Br], [(eta5-C5Me 5)Ru(PPh3)2Cl] and [(eta5-C 9H7)Ru(PPh3)2Cl] complexes react in presence of one equivalent of ligands 2-chloro-3-(pyrazolyl)quinoxaline (L 1) and di-(2-pyridyl)amine (L2) and one equivalent of NH4PF6 in methanol yielded mononuclear complexes [(eta5-C5H5)Ru(PPh3)(L 1)]PF6 (11), [(eta5-C5H 5)Os(PPh3)(L1)]PF6 (12), [(eta5-C5Me5)Ru(PPh3)(L 1)]PF6 (13) and [(eta5-C9H 7)Ru(PPh3)(L1)]PF6 (14) and [(eta5-C5H5)Ru(PPh3)(L 2)]PF6 (15), [(eta5-C5H 5)Os(PPh3)(L2)]PF6 (16), [(eta5-C5Me5)Ru(PPh3)(L 2)]PF6 (17) and [(eta5-C9H 7)Ru(PPh3)(L2)]PF6 (18) respectively. These compounds have been systematically characterized by IR, NMR and mass spectrometry. The molecular structures of 2, 4 and 15 have been established by single crystal X-ray diffraction study and some of the representative complexes have also been studied by UV-visible spectroscopy. The crystal packing diagram of complex 4 reveals that the cation [(eta6-C6H6)Ru(L2)Cl]+ is engaged in non-covalent interaction. This compound gives rise to a 1D helical architecture along the ‘a’ axis via intermolecular NH?Cl hydrogen bonds.
