Trans-4,5-bis(2-pyridyl)norbornane: A bidentate nitrogen ligand with a potentially large bite angle1

The coordination chemistry of the new chiral bidentate nitrogen ligand trans-4,5-bis(2-pyridyl)norbornane (Renorpy) towards palladium has been studied. The novel complexes (Renorpy)Pd(eta2-alkene) (eta2-alkene=maleic anhydride, tetracyanoethylene), (Renorpy)Pd(Me)Cl and (Renorpy)Pd(C(O)Me)Cl have been synthesized. Molecular modeling calculations gave a ‘natural’ bite angle for the Renorpy ligand of 115.5. Single crystal X-ray analyses of the complex (Renorpy)Pd(Me)Cl showed that the bite angle of the ligand in this complex is significantly smaller (93.7(2)) than the ‘natural’ one, which is caused by the electronic preference of palladium. To accommodate this smaller bite angle the palladium atom moves out of the pyridyl planes.

Anti-Markovnikov Hydroamination of Unactivated Alkenes with Primary Alkyl Amines

We report here a photocatalytic method for the intermolecular anti-Markovnikov hydroamination of unactivated olefins with primary alkyl amines to selectively furnish secondary amine products. These reactions proceed through aminium radical cation (ARC) intermediates and occur at room temperature under visible light irradiation in the presence of an iridium photocatalyst and an aryl thiol hydrogen atom donor. Despite the presence of excess olefin, high selectivities are observed for secondary over tertiary amine products, even though the secondary amines are established substrates for ARC-based olefin amination under similar conditions.

Palladium-Catalyzed Enantioselective Decarboxylative Allylic Alkylation of Protected Benzoin-Derived Enol Carbonates

The enantioselective palladium-catalyzed decarboxylative allylic alkylation of fully substituted alpha-hydroxy acyclic enol carbonates providing tetrasubstituted benzoin derivatives is reported. Investigation into the transformation revealed that preparation of the starting material as a single enolate isomer is crucial for optimal enantioselectivity. The obtained alkylation products contain multiple reactive sites that can be utilized toward the synthesis of stereochemically rich derivatives. (Figure presented.).

Strictly “pair”-selective and economical synthesis of conjugated diynes via Pd-catalyzed reaction of terminal alkynes with 1,1-dichloroethylene, elimination with LDA, and subsequent transformations

Various unsymmetrically substituted conjugated diynes can be synthesized in a completely “pair”-selective manner via Pd-catalyzed reaction of terminal alkynes with 1,1-dichloroethylene in the presence of Pd(PPh3)4 followed by elimination with 2 equiv of lithium diisopropylamide (LDA), zincation with ZnBrz or ZnCl2, and Pd-catalyzed cross-coupling with aryl and alkenyl iodides and bromides. The desired unsymmetrically substituted conjugated diynes have been obtained in >80% yields except in two cases where an alkenylzinc reagent generated in situ from (E)-3-iodo-2-propenol was used. The use of 1,1-dichloroethylene renders this method more economical than those involving 1,2-dihaloethylenes previously reported.

Monodentate Phosphorus Ligand-Enabled General Palladium-Catalyzed Allylic C-H Alkylation of Terminal Alkenes

Monodentate phosphorus ligands have been found to enable the palladium-catalyzed allylic C-H alkylation reaction of terminal alkenes with a wide variety of carbon nucleophiles. Moreover, an asymmetric allylic C-H alkylation of terminal alkenes with pyrazol-5-ones has been established in the presence of chiral phosphoramidite ligand and chiral phosphoric acid as co-catalyst. Mechanistic studies suggest that a ternary Pd(0) complex, coordinated with a monodentate phosphorus ligand, benzoquinone, and alkene, is most likely to be an active species.

Silylation and alkylation of allenes using chlorosilanes and alkyl halides in the presence of palladium catalyst and Grignard reagents

Allenes react with Grignard reagents and chlorosilanes in the presence of a palladium catalyst giving rise to carbosilylated products bearing carbon groups from Grignard reagents at the central carbon and silyl groups at the terminal carbon. When alkyl halides were used instead of chlorosilanes, the corresponding alkylated products were obtained.

Refolding and unfolding of CT-DNA by newly designed Pd(II) complexes. Their synthesis, characterization and antitumor effects

New antitumor Pd(II) compounds derived from oxygen donor ligands salicylate (SA) (1) and sulfosalicylate (SSA) (2) dianions and nitrogen donor heterocyclic ligand 2,2?-bipyridine (bpy) were synthesized and characterized by elemental analysis, UV?Vis, FT-IR, 1H NMR and conductivity measurements. The complexes evaluated for their cytotoxicity effects towards cancer cell line of K562 using MTT assay. They are more cytotoxic than cisplatin. The dependence of their interaction modes with CT-DNA on concentration of the compounds has been discovered in this work. CT-DNA binding studies of these complexes have been investigated by UV?Vis absorption, ethidium bromide (EB) displacement, fluorescence, circular dichroism and gel electrophoresis techniques. The apparent binding constants (Kapp) has been obtained 3.9 and 10.9?¡Á?104?M?1 at lower concentration range and 1.03 and 1.59?¡Á?104?M?1 at higher concentration range for complexes (1) and (2), respectively. These complexes effectively interact with CT-DNA in the order of (2)?>?(1). Fluorescence studies exhibited that the complexes quench CT-DNA-EB by simultaneous static and dynamic quenching processes. The calculated binding (Kapp, kq, KSV, n) and thermodynamic (DeltaG, DeltaH, DeltaS) parameters revealed that hydrophobic, van der Waals forces and hydrogen binding holds the Pd(II) complexes in the CT-DNA grooves. Gel electrophoresis supports the spectroscopic experiments.
