Nine-Membered Benzofuran-Fused Heterocycles: Enantioselective Synthesis by Pd-Catalysis and Rearrangement via Transannular Bond Formation

The first enantioselective formal [5+4] cycloaddition is realized under palladium catalysis to deliver benzofuran-fused nine-membered rings. These medium-sized heterocycles and derivatives undergo unique rearrangements induced by transannular bond formation, resulting in the production of two classes of densely substituted polycyclic heterocycles in excellent efficiency and stereoselectivity.

2- and 3-substituted imidazo[1,2-a]pyrazines as inhibitors of bacterial type IV secretion

A novel series of 8-amino imidazo[1,2-a]pyrazine derivatives has been developed as inhibitors of the VirB11 ATPase HP0525, a key component of the bacterial type IV secretion system. A flexible synthetic route to both 2- and 3-aryl substituted regioisomers has been developed. The resulting series of imidazo[1,2-a]pyrazines has been used to probe the structure-activity relationships of these inhibitors, which show potential as antibacterial agents.

An unexpected pathway for ligand substitution in an aryl halide complex of palladium

A supposed spectator ligand plays a crucial role in a seemingly simple ligand substitution reaction on palladium. Continuous monitoring by ESI-MS reveals all the details of an initial fast displacement of iodide by an incoming phosphine ligand, and of the recoordination of iodide that prompts the displacement of the bidentate ligand actually being substituted. An apparent double substitution and subsequent isomerization can be readily explained by two fast and one slow ligand substitution reactions (see figure). Copyright

High triplet energy crosslinkable hole transport material for blue phosphorescent organic light-emitting diodes

A high triplet energy crosslinkable hole transport material was developed for solution processed blue phosphorescent organic light-emitting diodes. A high triplet energy core structure, 3,3-di(9H-carbazol-9-yl)biphenyl, was functionalized with a vinylbenzene crosslinking unit to form the crosslinked hole transport layer. Crosslinking of the hole transport layer at 220 C produced an insoluble film which is stable under exposure to solvents. A blue emitting layer of iridium(III) bis(2-(4,6-difluorophenyl)-pyridinato-N,C2)picolinate doped diphenyldi(4-(9-carbazolyl)phenyl)silane was spin-coated on the crosslinked hole transport layer without damaging the underlying hole transport layer, which afforded solution processed blue phosphorescent organic light-emitting diodes with an external quantum efficiency of 19.1%.

Sequential Pyridine Dearomatization-Mizoroki-Heck Cyclization for the Construction of Fused (Dihydropyrido)isoindolinone Ring Systems

Acylation of 4-alkylpyridines with 2-iodobenzoyl chlorides under basic conditions results in pyridine dearomatization via formation of 4-alkylidene dihydropyridines. These reasonably stable intermediates are further transformed through Pd-catalyzed Mizoroki-Heck cyclization to afford dihydropyrido-fused isoindolinone products in good yield. This study demonstrates successful harnessing of reactive dearomatized pyridine anhydrobases in metal-catalyzed C-C bond-forming reactions, and provides an efficient entry to isoindolinone ring systems structurally related to several indolizidine alkaloid frameworks.

Synthesis of dinuclear palladium complexes having two parallel isocyanide ligands, and their application as catalysts to pyrrole formation from tert-butylisocyanide and alkynes

Novel dinuclear palladium complexes having two isocyanide ligands were synthesized by using a binucleating ligand, N,N?-bis[2-(diphenylphsphino)phenyl]formamidinate (dpfam). The structure of [Pd2(mu-dpfam)(tert-BuNC)2]Cl was confirmed by X-ray analysis, showing that the Pd-Pd bond length of 2.5824(3) A? falls well within the range of those for known dipalladium complexes having the edge-sharing structure and two isocyanides coordinate to palladium in almost parallel and in close proximity. The dinuclear complex [Pd2(mu-dpfam)(tert-BuNC)2]PF6 served as catalyst for pyrrole formation from tert-butylisocyanide and various alkynes.
