Synthesis and coordination chemistry of doubly-tridentate tripodal pyridazine and pyrimidine-derived ligands: Structural interplay between M 2L and M2L2 (M = Ni and Pd) complexes and magnetic properties of iron(II) complexes

The coordination chemistry of three bridging doubly-tridentate ligands, including the known compound 3,6-bis(di-2-pyridylmethyl)pyridazine (1), which is structurally similar to 1,4-bis(di-2-pyridylmethyl)phthalazine (2), and two pyrimidine-linked compounds 4,6-bis(di-2-pyridylmethyl)pyrimidine (3), and 4,6-bis(di-2-pyridylamino)pyrimidine (4), was investigated with FeII, NiII, and PdII metal salts. Ligands 3 and 4 were synthesized in one-pot reactions from easily obtained starting materials; compound 3 was synthesized from di-2-pyridylmethane and 4,6-diiodopyrimidine in 48% yield, while ligand 4 was prepared by reacting di-2-pyridylamine with 4,6-dichloropyrimidine in 27% yield. During the synthesis of 4, an additional compound, 4-chloro-6-(di-2-pyridylamino)pyrimidine (5), with only one tridentate binding site was obtained in 30% yield. Reactions of 1, 3, and 4 with Fe II or NiII salts gave two types of complexes, either discrete M2L or M2L2 assemblies. The Pd II complexes obtained were also characterized as discrete M 2L complexes. The compounds were characterized by a combination of NMR and IR spectroscopy, microanalysis and X-ray crystallography. Noticeable differences in the structures obtained for NiII coordination complexes with the carbon-linked (3) and nitrogen-linked (4) ligands were observed, whereby the nitrogen linker adopted a trigonal planar geometry and prevented tridentate facial coordination of the octahedral metal centres. The magnetic properties of dinuclear FeII complexes of 1 were examined to see if they showed spin-crossover effects, a feature recently observed by others in other dinuclear helicate complexes, but the complexes remained high-spin at all temperatures between 300 and 2 K.

Discovery of Orally Bioavailable and Liver-Targeted Hypoxia-Inducible Factor Prolyl Hydroxylase (HIF-PHD) Inhibitors for the Treatment of Anemia

We report herein the design and synthesis of a series of orally active, liver-targeted hypoxia-inducible factor prolyl hydroxylase (HIF-PHD) inhibitors for the treatment of anemia. In order to mitigate the concerns for potential systemic side effects, we pursued liver-targeted HIF-PHD inhibitors relying on uptake via organic anion transporting polypeptides (OATPs). Starting from a systemic HIF-PHD inhibitor (1), medicinal chemistry efforts directed toward reducing permeability and, at the same time, maintaining oral absorption led to the synthesis of an array of structurally diverse hydroxypyridone analogues. Compound 28a was chosen for further profiling, because of its excellent in vitro profile and liver selectivity. This compound significantly increased hemoglobin levels in rats, following chronic QD oral administration, and displayed selectivity over systemic effects.

Remarkable effects of axial pi* coordination on the Cr-Cr quadruple bond in dichromium paddlewheel complexes

It is well-known that donation of electron density into the sigma* orbital of a Cr-Cr quadruple bond causes major lengthening of the Cr-Cr distance, and there is some prior evidence that a similar lengthening is caused by dative interaction with the pi* orbitals. Some molecules have now been made that allow a definitive assessment of this axial pi* effect. A molecule has been designed to ensure that there is axial donation into the pi* orbitals but not onto the sigma* orbital; ligands have been used in which the donor atoms are tethered to the bridging ligands in such a way that they can reach only the pi* orbitals but not the sigma* orbital. The ligands used for this purpose are the anions of 2,6-di(phenylimino)piperidine (DPhIP) and 2,2?-dipyridylamine (dpa). In the compound Cr2(DPhIP)4 four imino nitrogen lone pairs are suitably positioned to donate to the pi* orbitals and the Cr-Cr bond length is 2.265(1) A. For direct comparison, the compound Cr2(PhIP)4 (PhIP is the anion of 2-(phenylimino)piperidine) was made and found to have a Cr-Cr distance of 1.858(1) A. In this case the ligand is very similar to DPhIP except that it has no donor nitrogen atoms available for axial pi* donation. Thus, the cumulative effect of donation from four nitrogen atoms is very large, namely, 0.4 A in the Cr-Cr distance. The Cr2(dpa)4 molecule occurs in three different crystalline compounds, in all of which there are slightly different conformations, but the same Cr-Cr distance, 1.94 ¡À 0.01 A; these may be compared to that in the compound Cr2(mpa)4 (1.87 A) in which the bridging is quite similar but there are no tethered additional donor atoms.

Transition-Metal-Catalyzed Transformation of Sulfonates via S-O Bond Cleavage: Synthesis of Alkyl Aryl Ether and Diaryl Ether

The catalytic conversion of sulfonates, a versatile class of pharmaceutical intermediates, is usually based on C-O bond cleavage. In this paper, however, we discover a rare transformation of sulfonates via S-O bond cleavage catalyzed by transition metal, through which alkyl sulfonates could undergo an intramolecular desulfitative C-O coupling to form aryl alkyl ethers in the presence of a nickel catalyst. Meanwhile, aryl sulfonates perform similarly to give diaryl ethers catalyzed by a palladium complex. This transformation could tolerate a wide range of functionalities. Controlled experiments reveal that the 2-pyridyl group is necessary to promote the reaction as designed. Crossover experiments proved that this transformation might proceed partly in an intermolecular pathway.
