Palladium-Catalyzed Carboamination of Allylic Alcohols Using a Trifluoroacetaldehyde-Derived Tether

The selective palladium-catalyzed carboamination of allylic alcohols is reported on the basis of the use of an easily introduced trifluoroacetaldehyde-derived tether. Aminoalkynylation reactions were realized using alkynyl bromides and commercially available phosphine ligands. For aminoarylations, a new biaryl phosphine ligand, “Fu-XPhos”, was introduced to overcome a competitive Heck pathway. The carboamination products were obtained in high yields and diastereoselectivity. The tether could be easily removed to give value-added amino alcohol building blocks.

Fluorous-Phase Approach to alpha-Hydroxytropolone Synthesis

alpha-Hydroxytropolones (alphaHTs) are troponoids that demonstrate inhibition against an array of therapeutically significant targets, making them potential drug leads for several human diseases. We have utilized a recently discovered one-pot three-component oxidopyrylium cycloaddition in a solid-supported synthesis of alphaHTs. Though the procedure is time efficient and generates assay-ready molecules, the system suffers from low yields and an inability to perform reaction modifications on resin-bound intermediates. In order to combat these issues with the solid-phase platform, we incorporated fluorous tags into our synthetic route. Through the implementation of fluorous phase chemistry, we demonstrate a substantial increase in the overall yield of alphaHTs, as well as an ability to execute metal-catalyzed cross coupling and amide coupling on fluorous tagged intermediates. We also show that tagged molecules can be separated from nonfluorous impurities, and vice versa, by utilizing fluorous liquid-liquid and solid-phase extractions. Hence, these proof-of-principle investigations describe the viability of a fluorous phase approach to alphaHT synthesis and its potential to serve as a combinatorial technique to produce structurally diverse substrates.

Iron(II) versus osmium(II) oxidation in 1,1?-bis(diorganophosphino)ferrocene-osmium(II) complexes

The compounds [(Cym)OsCl(dxpf)](PF6), Cym=p-cymene and dxpf: 1,1?-bis(diphenylphosphino)ferrocene (dppf), 1,1?-bis(diethylphosphino)ferrocene (depf) or 1,1?-bis(diisopropylphosphino)ferrocene (dippf), were synthesized and characterized by NMR (1H, 31P) and, in the case of [(Cym)OsCl(dppf)](PF6), by X-ray structure analysis of the acetonitrile solvate. EPR and UV-vis spectroelectrochemistry indicate the formation of an osmium(II)-ferrocenium species on reversible one-electron oxidation. The second oxidation and the reduction are electrochemically irreversible.

Super-resolution imaging of lysosomes with a nitroso-caged rhodamine

Caged-fluorophores are potentially suitable for photo-activated localization microscopy (PALM) for super-resolution imaging. N-Nitroso is a simple and robust photo-cage with biocompatible nitric oxide as the only byproduct upon photolysis. We herein reported a novel PALM probe (NOR535) for super-resolution imaging of lysosomes with high localization precision.

Synthesis by direct arylation of thiazole-derivatives: Regioisomer configurations-optical properties relationship investigation

The synthesis of thiazole(Tz)-based regioisomer materials using selective direct arylation to avoid any protection steps has been developed. A series of trimers in which the Tz groups sandwich either an electron-rich or an electron-deficient unit, with a regioselective orientation of the respective Tz unit, has therefore been synthesized. This chemical strategy has also been followed to synthesize a second series of pentamers in which the Tz group is used as a conjugated bridge between an electron-rich central unit and electron-deficient end-capping groups and vice versa. On both trimers and pentamers, the effect of Tz orientation on the conjugation properties of the synthesized materials was investigated by a combination of experimental measurements and density functional theory calculations. This study highlights that control of the orientation of the Tz unit leads to the synthesis of the most conjugated regioisomer derivative. The present work gives chemical synthesis tools for the synthesis of selectively oriented Tz-based materials as well as a general guideline for the design of Tz-based materials with the highest conjugation length, including the Tz-orientation effect.

Human Serum Albumin-Delivered [Au(PEt3)]+ Is a Potent Inhibitor of T Cell Proliferation

Using a modular library format in conjunction with cell viability (MTS) and flow cytometry assays, 90 cationic complexes [AuPL]n+ (P = phosphine ligand; L = thiourea derivative or chloride) were studied for their antiproliferative activity in CD8+ T lymphocyte cells. The activity of the compounds correlates with the steric bulk of the phosphine ligands. Thiourea serves as a leaving group that is readily replaced by cysteine thiol (NMR, ESI-MS). Taking advantage of selective thiourea ligand exchange, the fragments [Au(PEt3)]+ and [Au(JohnPhos)]+ (JohnPhos = 1,1?-biphenyl-2-yl)di-tert-butylphosphine) in compounds 1 and 2 were transferred to recombinant human serum albumin (rHSA). PEt3 promoted efficient modification of Cys34 in HSA (HSA-1), whereas use of bulky JohnPhos as a carrier ligand led to serum protein nonspecifically modified with multiple gold adducts (HSA-2) (Ellman?s test, ESI-TOF MS). HSA-1, but not HSA-2, strongly inhibits T cell proliferation at nanomolar doses. The potential role of HSA as a delivery vehicle in gold-based autoimmune disease treatment is discussed.
