Synthesis and structure-activity data of some new epibatidine analogues

The high-pressure Diels-Alder reaction of N-carbomethoxypyrroles and phenyl vinyl sulfone affords versatile intermediates for the palladium-catalyzed preparation of new epibatidine analogues. Structure-activity relationships of new epibatidine analogues are presented. High affinities of K(i)=0.81 and 2.6nM for the [3H]-cytisine rat brain nicotinic acetylcholine binding sites were found for the 5-pyrimidinyl and the 5-(2-amino)-pyrimidinyl epibatidine analogues, respectively.

Ir(iii)-catalyzed: Ortho C-H alkylations of (hetero)aromatic aldehydes using alkyl boron reagents

Transition-metal-catalyzed C-H alkylation reactions directed by aldehydes or ketones have been largely restricted to electronically activated alkenes. Herein, we report a general protocol for the Ir(iii)-catalyzed ortho C-H alkylations of (hetero)aromatic aldehydes using alkyl boron reagents as the coupling partner. Featuring aniline as an inexpensive catalytic ligand, the method was compatible with a wide variety of benzaldehydes, heterocyclic aldehydes, potassium alkyltrifluoroborates as well as a few alpha,beta-unsaturated aldehydes. An X-ray crystal structure of a benzaldehyde ortho C-H iridation intermediate was also successfully obtained.

Regioselective Cyanation of Six-Membered N-Heteroaromatic Compounds Under Metal-, Activator-, Base- and Solvent-Free Conditions

A regioselective cyanation of heteroaromatic N-oxides with trimethylsilyl cyanide has been developed to obtain 2-substituted N-heteroaromatic nitrile without the requirement of any external activator-, metal-, base-, and solvent. The present protocol is a straightforward, one-pot heteroaromatic C?H cyanation process, and proceeds smoothly in conventional heating but also under microwave irradiation with shorter reaction times. This approach now allows access to a broad class of quinoline N-oxides and other heteroarene N-oxides with high to good yields and can also be scaled up to obtain gram quantities. Further application of this process was observed and utilized in late-stage cyanation of the anti-malarial drug quinine as well as transformation of the 2-cyanoazines to a series of biologically important molecules. Based on the experimental observations, a plausible mechanism has also been proposed highlighting the dual role of trimethylsilyl cyanide as a nitrile source and as an activating agent.

Synthesis and photophysical properties of cyclometalated platinum(II) 1,2-benzenedithiolate complexes and heterometallic derivatives obtained from the addition of [Au(PCy3)]+ units

The cyclometalated compounds [Pt(C^N)(HC^N)Cl] [HC^N = 2-phenylpyridine (Hppy; 1a), 1-(4-tert-butylphenyl)isoquinoline (Htbpiq; 1b)] react with 1,2-benzenedithiol, t-BuOK, and Bu4NCl in a 1:1:2:1 molar ratio in CH2Cl2/MeOH to give the complexes Bu4N[Pt(C^N) (bdt)] [bdt = 1,2-benzenedithiolate; C^N = ppy (Bu4N2a), tbpiq (Bu4N2b)]. In the absence of Bu4NCl, the same reactions afford solutions of K2a and K2b, which react with [AuCl(PCy3)] to give the neutral heterometallic derivatives [Pt(C^N)(bdt){Au(PCy3)}] [C^N = ppy (3a), tbpiq (3b)]. The cationic derivatives [Pt(C^N)(bdt){Au(PCy 3)}2]ClO4 [C^N = ppy (4a), tbpiq (4b)] are obtained by reacting 3a and 3b with acetone solutions of [Au(OClO 3)(PCy3)]. The crystal structures of 3b and 4b reveal the formation of short Pt???Au metallophilic contacts in the range 2.929-3.149 A. Complexes 3b, 4a, and 4b undergo dynamic processes in solution that involve the migration of the [Au(PCy3)]+ units between the S atoms of the dithiolate. Complexes Bu4N2a and 2b display a moderately solvatochromic band in their electronic absorption spectra that can be ascribed to a transition of mixed ML?CT/LL?CT character (M= metal; L = bdt; L? = C^N; CT = charge transfer), while their emissions are assignable to transitions of the same orbital parentage but from triplet excited states. The successive addition of [Au(PCy3)]+ units to the anions 2a and 2b results in an increase in the absorption and emission energies attributable to lower highest occupied molecular orbital energies. Additionally, the characteristics of the absorption and emission spectra of the heterometallic derivatives indicate a gradual loss of LL?CT character in the involved electronic transitions, with a concomitant increase of the L?C and ML?CT contributions.

Fabrication and Application of Graphene Supported Diimine-Palladium Complex Catalyst for Organic Synthesis

In this paper, a diimine palladium complex with suitable steric hindrance of isopropyl groups and electron supply provides excellent protection for palladium active centers was synthesized and anchored on graphene oxide (GO) to obtain a reusable heterogeneous catalyst (Pd-DI@GO). The XPS results confirmed the effective loading of palladium and the interaction between palladium and ligand. The ICP-AES data verified the Pd content of catalyst was 5.04 wt% and confirmed extremely small amount Pd leaching in Suzuki reaction (<1 ppm). The Pd-DI@GO can catalyze Suzuki reaction under milder conditions and afford 39 reactants with high yields (79%?99%). It can achieve a yield as high as 99% with heterocyclic compound reactants which can poison the catalyst. The yields of double and triple substitutions are also impressive (70?92%). The Pd-DI@GO can catalyze the C?H direct arylation reaction efficiently, affording 22 reactants with superior yields (>85%). Notably, the Pd-DI@GO can be recycled after Suzuki reaction via filtration or centrifugation easily, presenting a yield above 90% for the 4th run.
