A Dipolar Anthracene Dye: Synthesis, Optical Properties and Two-photon Tissue Imaging

Two-photon microscopy is a powerful tool for studying biological systems. In search of novel two-photon absorbing dyes for bioimaging, we synthesized a new anthracene-based dipolar dye (anthradan) and evaluated its two-photon absorbing and imaging properties. The new anthradan, 9,10-bis(o-dimethoxy-phenyl)-anthradan, absorbs and emits at longer wavelengths than acedan, a well-known two-photon absorbing dye. It is also stable under two-photon excitation conditions and biocompatible, and thus used for two-photon imaging of mouse organ tissues to show bright, near-red fluorescence along with negligible autofluorescence. Such an anthradan thus holds promise as a new class of two-photon absorbing dyes for the development of fluorescent probes and tags for biological systems.

Discovery and Computational Rationalization of Diminishing Alternation in [n]Dendralenes

The [n]dendralenes are a family of acyclic hydrocarbons which, by virtue of their ability to rapidly generate structural complexity, have attracted significant recent synthetic attention. [3]Dendralene through [8]dendralene have been previously prepared but no higher member of the family has been reported to date. Here, we describe the first chemical syntheses of the “higher” dendralenes, [9]dendralene through [12]dendralene. We also report a detailed investigation into the spectroscopic properties and chemical reactivity of the complete family of fundamental hydrocarbons, [3]dendralene to [12]dendralene. These studies reveal the first case of diminishing alternation in behavior in a series of related structures. We also report a comprehensive series of computational studies, which trace this dampening oscillatory effect in both spectroscopic measurements and chemical reactivity to conformational preferences.

Cobalt-Catalyzed 1,1-Diboration of Terminal Alkynes: Scope, Mechanism, and Synthetic Applications

A cobalt-catalyzed method for the 1,1-diboration of terminal alkynes with bis(pinacolato)diboron (B2Pin2) is described. The reaction proceeds efficiently at 23 C with excellent 1,1-selectivity and broad functional group tolerance. With the unsymmetrical diboron reagent PinB-BDan (Dan = naphthalene-1,8-diaminato), stereoselective 1,1-diboration provided products with two boron substituents that exhibit differential reactivity. One example prepared by diboration of 1-octyne was crystallized, and its stereochemistry established by X-ray crystallography. The utility and versatility of the 1,1-diborylalkene products was demonstrated in a number of synthetic applications, including a concise synthesis of the epilepsy medication tiagabine. In addition, a synthesis of 1,1,1-triborylalkanes was accomplished through cobalt-catalyzed hydroboration of 1,1-diborylalkenes with HBPin. Deuterium-labeling and stoichiometric experiments support a mechanism involving selective insertion of an alkynylboronate to a Co-B bond of a cobalt boryl complex to form a vinylcobalt intermediate. The latter was isolated and characterized by NMR spectroscopy and X-ray crystallography. A competition experiment established that the reaction involves formation of free alkynylboronate and the two boryl substituents are not necessarily derived from the same diboron source.

The Palladium-Catalyzed Heteroarylation of Adamantylalkyl Amines with Dihalogenopyridines: Scope and Limitations

Palladium-catalyzed heteroarylation of adamantylalkyl amines characterized by different steric hindrances at the amino group was carried out using 2,3-, 2,5-, 2,6-, and 3,5-dihalogenopyridines. The dependence of the results of the coupling on the nature of the halogen atoms (bromine, chlorine), their position in the pyridine ring, and on the structure of adamantylalkyl amines was investigated. The application of dichloropyridines or bromochloropyridines was shown to be advantageous over the use dibromopyridines in many cases. Selective substitution of bromine atom in positions 3 and 5 in the presence of chlorine atom in position 2 of the pyridine ring was observed. The possibility of N, N -diheteroarylation of adamantane-containing amines with 2,5-dihalogenopyridines was shown, and diamination of 2,6- and 3,5-dihalogenopyridines was demonstrated.

Homo-and heterobimetallic Pd-, Ag-, and Ni-hybrid salen-bis-NHC complexes

salen ligands and N-heterocyclic carbenes (NHC) are among the most abundant structural ligand motifs for metal catalysis. In this article we present a modular approach to chiral ligands merging both ligand motifs for the preparation of bimetallic catalysts, in which one metal (M1) is coordinated by the salen moiety and the other metal (M2) binds to two NHCs. After selective complexation of M1 = PdII, Ni II ion into the salen N2O2 coordination site, heterobimetallic M1/Ag(I) complexes were synthesized which could be further utilized for the preparation of homo-and heterobimetallic M 1/PdII complexes by an oxidative transmetalation to Pd(0) as a key step of the catalyst synthesis. The structures of the bimetallic complexes and the intermetallic distances strongly depend on the counterions of M2 = PdII, as revealed by X-ray and UV-vis studies. In the absence of an anionic ligand with suitable Lewis basicity the salen oxygen atoms serve as bridging ligands for both metals. A preliminary investigation into catalysis showed that the complexes are capable of catalyzing the 1,4-addition of oxindoles to 2-nitrostyrene.

Homochiral Emissive Lambda8- and Delta8-[Ir8Pd4]16+ Supramolecular Cages

Synthetic self-assembly is a powerful technique for the bottom-up construction of discrete and well-defined polyhedral nanostructures resembling the spherical shape of large biological systems. In recent years, numerous Archimedean-shaped coordination cages have been reported based on the assembly of bent monodentate organic ligands containing two or more distal pyridyl rings and square-planar PdII ions. The formation of photoactive PdII metallamacrocycles and cages, however, remain rare. Here we report the first examples of emissive and homochiral supramolecular cages of the form [Ir8Pd4]16+. These cages provide a suitably sized cavity to host large guest molecules. Importantly, encapsulation and energy transfer have been observed between the blue-emitting NBu4[Ir(dFppy)2(CN)2] guest and the red-emitting Delta8-[Ir8Pd4]16+ cage.

The cytotoxicity and mechanism of action of new multinuclear Scaffold AuIII, PdII pincer complexes containing a bis(diphenylphosphino) ferrocene/non-ferrocene ligand

New multinuclear gold(iii), palladium(ii) pincer complexes containing bis(diphenylphosphino) ferrocene/non-ferrocene ligands of formula [(L)Au(mu2-eta2-CS3)Pd(dppf)](PF6)2, 1, and [(L)Au(mu2-eta2-CS3)Pd(dppe)](PF6)2, 2 (HL = 5-methoxy-1,3-bis (1-methyl-1H-benzo[d]imidazol-2-yl)benzene, dppf = 1,1?-bis(diphenylphosphino)ferrocene, and dppe = bis(diphenylphosphino)ethane) have been synthesized and fully characterized. Both complexes are more cytotoxic to a number of human cancer cell lines than cisplatin. Moreover, complex 1 is more active than auranofin as the reference gold compound against a panel of several human tumor cell lines. Chemosensitivity tests completed on cisplatin sensitive and resistant cell lines have confirmed that both complexes were able to overcome cisplatin resistance. The complexes successfully inhibited the enzymes thioredoxin reductase (TrxR) and glutathione reductase (GR). The cellular uptake of both gold and palladium of the complexes was studied, which indicated a high biological stability of the complexes. The complexes 1 and 2 increase the production of ROS in HCT-15 cells. In addition, these complexes induce major levels of cancer cell death by apoptosis.

Convenient synthesis of 1H-indol-1-yl boronates via palladium(0)-catalyzed borylation of bromo-1H-indoles with ‘pinacolborane’

An atom-economic Pd0-catalyzed synthesis of a series of pinacol-type indolylboronates 3 from the corresponding bromoindole substrates 2 and pinacolborane (pinBH) as borylating agent was elaborated. The optimal catalyst system consisted of a 1:2 mixture of [Pd(OAc)2] and the ortho-substituted biphenylphosphine ligand L-3 (Scheme 4, Table). Our synthetic protocol was applied to the fast, preparative-scale synthesis of 1-substituted indolylboronates 3a-h in the presence of different functional groups, and at a catalyst load of only 1 mol-% of Pd.
