Transition-state stabilization by a secondary substrate-ligand interaction: A new design principle for highly efficient transition-metal catalysis

A library of monodentate phosphane ligands, each bearing a guanidine receptor unit for carboxylates, was designed. Screening of the library gave some excellent catalysts for regioselective hydroformylation of ss,gamma- unsaturated carboxylic acids. A terminal alkene, but-3-enoic acid, was hydroformylated with a linear/branched (l/b) regioselectivity up to 41. An internal alkene, pent-3-enoic acid was hydroformylated with regioselectivity up to 18:1. Further substrate selectivity (e.g., acid vs. methyl ester) and reaction site selectivity (monofunctionalization of 2- vinylhept-2-enoic acid) were also achieved. Exploration of the structure-activity relationship and a practical and theoretical mechanistic study gave us an insight into the nature of the supramolecular guanidinium-carboxylate interaction within the catalytic system. This allowed us to identify a selective transition-state stabilization by a secondary substrate-ligand interaction as the basis for catalyst activity and selectivity.

2-(Diphenylphosphino)benzoyl-substituted calix[4]arene: Efficient organocatalyst in aza-Morita-Baylis-Hillman reaction of N-sulfonated imines with methyl vinyl ketone

A novel bifunctional organocatalyst 5,11,17,23-tetra-butyl-25-[2- (diphenylphosphino)benzoate]-26,27,28-trihydroxycalix-[4]arene (LB3) was synthesized and applied to promote the aza-Morita-Baylis-Hillman (aza-MBH) reaction of N-sulfonated im-ines with methyl vinyl ketone. It was found that in the presence of acidic additives the reaction rate could be accelerated to give aza-MBH adducts in good to excellent yields. Compared to our previous phosphine-containing calix[4]arene LB1, the novel catalyst was more effective. Georg Thieme Verlag Stuttgart · New York.

Ruthenium arene complexes with triphenylphosphane ligands: Cytotoxicity towards pancreatic cancer cells, interaction with model proteins, and effect of ethacrynic acid substitution

The ruthenium-arene complexes [(eta6-p-cymene)RuCl2(kappaP-PPh2(4-C6H4CO2H))], 1, [(eta6-p-cymene)RuCl(kappa2P,O-PPh2(2-C6H4CO2))], 2, [(eta6-p-cymene)RuCl2(kappaP-PPh2(2-C6H4OCO-EA))], 3, and [(eta6-p-cymene)RuCl2(kappaP-PPh2(4-C6H4CO2CH2CH2OCO-EA))], 4 (EA-CO2H = ethacrynic acid), were synthesized in good to high yields and characterized by analytical techniques, IR, UV-Vis and multinuclear NMR spectroscopy, and single crystal X-ray diffraction in the cases of 1 and 2. The unstable compounds [(eta6-arene)RuCl2(kappaP-PPh2(2-C6H4CO2CH2CH2OCO-EA))] (arene = p-cymene, 5a; arene = C6H6, 5b) were obtained and identified in solution by NMR. Electrochemical and spectro-electrochemical experiments were performed in order to assess the redox behaviour of 1-4 in CH2Cl2. The in vitro cytotoxicity of 1-4 was determined on the human pancreatic cancer cell line BxPC3 and the mouse embryo fibroblast Balb/3T3 Clone A31 cell line, the latter acting as a model for normal cells. Furthermore, the interaction of 1, 3 and 4 with two model proteins was investigated by high resolution ESI-MS.

RNA Cloaking by Reversible Acylation

We describe a selective and mild chemical approach for controlling RNA hybridization, folding, and enzyme interactions. Reaction of RNAs in aqueous buffer with an azide-substituted acylating agent (100?200 mm) yields several 2?-OH acylations per RNA strand in as little as 10 min. This poly-acylated (?cloaked?) RNA is strongly blocked from hybridization with complementary nucleic acids, from cleavage by RNA-processing enzymes, and from folding into active aptamer structures. Importantly, treatment with a water-soluble phosphine triggers a Staudinger reduction of the azide groups, resulting in spontaneous loss of acyl groups (?uncloaking?). This fully restores RNA folding and biochemical activity.

Dual-Site Fluorescent Probe to Monitor Intracellular Nitroxyl and GSH-GSSG Oscillations

Nitroxyl (HNO), the one-electron-reduction product of NO has recently been revealed to have potentially beneficial pharmacological properties in cardiovascular health as a result of interactions with specific thiols such as glutathione (GSH). To disentangle the complicated inter-relationship between HNO and GSH in the signal transduction and oxidative pathways, we designed and synthesized a dual-site fluorescent probe NCF to indicate cellular HNO and GSH-GSSG balance. The sensitive and selective detection of HNO was achieved by incorporating an organophosphine group to naphthaldehyde-TCF. Then the resulted fluorescent product is able to monitor the conversion of GSH and GSSG reversibly. Additionally, outstanding biocompatibility make it capable of monitoring intracellular HNO and consequently GSH-GSSG oscillationsin living cells. We anticipate that NCF will be a unique molecular tool to investigate the interplaying roles of HNO and GSH.
