Architecture of Crystalline Polymers Formed from the Binuclear Complexes XAuPh2P(CH2)nPPh2AuX through Weak Au(I)…Au(I) Interactions

A systematic study is reported of the effects of weak attractive AuI…Au interactions on the solid state structures of six crystalline polymers from molecules of the type XAuP/zPAuX, where X is iodide or chloride and PnP is Ph2P(CH2)nPPh2 with n = 4-8. Crystallographic data for the six molecules IAuP4PAuI, IAuP5PAuI, IAuP6PAuI, ClAuP7PAuCl¡¤CH3OH, IAuP8PAuI¡¤CH2Cl2, and ClAuP8PAuCl¡¤CH2Cl2 are presented. In each case, the complexes appear to be symmetrical monomeric species in solution, as shown by the simple, single-line 31P NMR spectra. However, they form linear chains in the solid state with individual molecules connected through close Au…Au contacts at each end of the molecule. These solids are analyzed in terms of the structures of individual molecules, geometries of Au…Au interactions, methods of chain propagation, and relative orientations of individual chains. Only two types of propagation (pure translation and translation along a glide plane) of individual molecules are observed. The chains arrange themselves in three motifs: strands that run parallel, layers of strands that criss-cross, and layers with an interwoven strand structure.

Dearomatization Strategy for the Synthesis of Arylated 2H-Pyrroles and 2,3,5-Trisubstituted 1H-Pyrroles

The first high-yielding route to arylated 2H-pyrroles was developed. The methodology utilizes 2,5-disubstituted pyrroles that are metalated, and the aryl substituents are introduced by a palladium-catalyzed cross-coupling reaction. The prepared pyrroles can be rearranged to 2,3,5-trisubstituted pyrroles under acidic conditions. Attempts to convert the 2,3,5-trisubstituted pyrroles to 2,3,4,5-tetrasubstituted pyrroles by the dearomatization rearrangement strategy were unsuccessful.

A series of novel (NHC)PdCl2-PR3 complexes were synthesized and fully characterized by 1H, 13C, 31P NMR and FT-IR spectroscopy. These complexes showed high catalytic activity toward solvent-free Buchwald-Hartwig amination. Both primary and secondary amines were efficiently utilized under the same reaction conditions. The solvent-free synthesis of valuable N-aryl carbazoles and similar N-heterocyclic systems was described.

Hypoxia-selective radiosensitisation by SN38023, a bioreductive prodrug of DNA-dependent protein kinase inhibitor IC87361

DNA-dependent protein kinase (DNA-PK) plays a key role in repair of radiation-induced DNA double strand breaks (DSB) by non-homologous end-joining. DNA-PK inhibitors (DNA-PKi) are therefore efficient radiosensitisers, but normal tissue radiosensitisation represents a risk for their use in radiation oncology. Here we describe a novel prodrug, SN38023, that is metabolised to a potent DNA-PKi (IC87361) selectively in radioresistant hypoxic cells. DNA-PK inhibitory potency of SN38023 was 24-fold lower than IC87361 in cell-free assays, consistent with molecular modelling studies suggesting that SN38023 is unable to occupy one of the predicted DNA-PK binding modes of IC87361. One-electron reduction of the prodrug by radiolysis of anoxic formate solutions, and by metabolic reduction in anoxic HCT116/POR cells that overexpress cytochrome P450 oxidoreductase (POR), generated IC87361 efficiently as assessed by LC-MS. SN38023 inhibited radiation-induced Ser2056 autophosphorylation of DNA-PK catalytic subunit and radiosensitised HCT116/POR and UT-SCC-54C cells selectively under anoxia. SN38023 was an effective radiosensitiser in anoxic HCT116 spheroids, demonstrating potential for penetration into hypoxic tumour tissue, but in spheroid co-cultures of high-POR and POR-null cells it showed no evidence of bystander effects resulting from local diffusion of IC87361. Pharmacokinetics of IC87361 and SN38023 at maximum achievable doses in NIH-III mice demonstrated sub-optimal exposure of UT-SCC-54C tumour xenografts and did not provide significant tumour radiosensitisation. In conclusion, SN38023 has potential for exploiting hypoxia for selective delivery of a potent DNA-PKi to the most radioresistant subpopulation of cells in tumours. However, prodrugs providing improved systemic pharmacokinetics and that release DNA-PKi that elicit bystander effects are needed to maximise therapeutic utility.

Gold(I)-Catalysed Hydroarylation of 1,3-Disubstituted Allenes with Efficient Axial-to-Point Chirality Transfer

Hydroarylation of enantioenriched 1,3-disubstituted allenes has the potential to proceed with axial-to-point chirality transfer to yield enantioenriched allylated (hetero)aryl compounds. However, the gold-catalysed intermolecular reaction was previously reported to occur with no chirality transfer owing to competing allene racemisation. Herein, we describe the development of the first intermolecular hydroarylations of allenes to proceed with efficient chirality transfer and summarise some of the key criteria for achieving high regio- and stereoselectivity.

(alpha-Diimine)nickel Complexes That Contain Menthyl Substituents: Synthesis, Conformational Behavior, and Olefin Polymerization Catalysis

We describe the synthesis and coordination chemistry of the (1R,2S,5R)-menthyl-substituted N,N?-diaryl-alpha-diimine ligands N,N?-(2-Men-4-Me-Ph)2-BIAN (L1, Men = menthyl, BIAN = bis(imino)acenaphthene) and N,N?-(2-Men-4,6-Me2-Ph)2-BIAN (L2), the conformational properties of these ligands and their metal complexes, and the ethylene and 1-hexene polymerization behavior of the corresponding (alpha-diimine)Ni complexes. Free ligands L1 and L2 and square-planar (L1)PdCl2 and (L1,2)Ni(acac)+ complexes exhibit a preference for the syn conformation, in which the two menthyl units are located on the same side of the N=N plane, while tetrahedral (L1,2)MX2 (MX2 = ZnCl2, NiBr2) complexes exhibit a preference for the anti conformation, in which the menthyl units are located on opposite sides of the N=N plane. Both the anti and the syn conformers of [(L2)Ni(acac)][B(C6F5)4] can be activated by Et2AlCl to generate highly active ethylene polymerization catalysts (activity (2.5-6.6) ¡Á 106 g of PE/((mol of Ni) h) at 15 psi of C2H4, room temperature). The polyethylene produced by the syn conformer (syn/anti = 91/9) has a higher molecular weight (2¡Á) and a higher branch density (3¡Á) in comparison to that produced by the anti conformer. The polyhexene produced by the syn conformer (syn/anti = 91/9) contains a higher level of chain straightening (syn 50%, anti 41%) and a higher percentage of Me versus Bu branches (syn 24/26, anti 6/53) in comparison to that produced by the anti isomer. These results are indicative of a greater preference for 2,1-insertion and for chain walking (versus growth) following 1,2-insertion for the syn conformer.
